A second monoclinic polymorph of (E)-phen-yl(pyridin-2-yl)methanone oxime.

ABSTRACT: The title compound, C(12)H(10)N(2)O, a second monoclinic poly-morph of (E)-phen-yl(pyridin-2-yl)methanone oxime crystallizes in the space group P2(1)/n (Z = 4). The previously reported polymorph [Taga et al. (1990 ▶). Acta Cryst. C46, 2241-2243] occurs in the space group C2/c (Z = 8). In the crystal, pairs of bifurcated O-H⋯(N,O) hydrogen bonds link the mol-ecules into inversion dimers. The dimers are linked by C-H⋯π inter-actions, forming a linear arrangement. The dihedral angle between the pyridine and phenyl rings is 67.70 (8)°.

N-(2-Formyl-phen-yl)-4-toluene-sulfonamide: a second monoclinic polymorph.

Project description:The title compound, C(14)H(13)NO(3)S, (I), is a second monoclinic polymorph. The original polymorph, (II), was reported by Mahía et al. [Acta Cryst. (1999), C55, 2158-2160]. Polymorph (II) crystalllized in the space group P2(1)/c (Z = 4), whereas the title polymorph (I) occurs in the space group P2(1)/n (Z = 4). The dihedral angle between the two aromatic rings is 75.9 (1)° in (I) compared to 81.9 (1)° for (II). In both polymorphs, two S(6) rings are generated by intra-molecular N-H⋯O and C-H⋯O hydrogen bonds, resulting in similar mol-ecular geometries. However, the two polymorphs differ concerning their crystal packing. In (I), mol-ecules are linked into C(8) zigzag chains along the b axis by C-H⋯O hydrogen bonds, whereas in (II) mol-ecules are linked by C-H⋯O hydrogen bonds, forming C(7) chains along the b axis. The title polymorph is further stabilized by inter-molecular C-H⋯π and π-π inter-actions [centroid-centroid distance = 3.814 (1) Å]. These inter-actions are not evident in polymorph (II).

A second monoclinic polymorph of N-(2,4-dinitro-phen-yl)-2,4-dinitro-aniline.

Project description:The title compound, C(12)H(7)N(5)O(8), was previously described in space group P2(1)/n with Z = 4 [Wu et al. (2007 ▶). Acta Cryst. E63, o4194]. The current monoclinic P2(1)/c polymorph was obtained from a mixed solution of dichloro-methane and hexane. The dihedral angle between the benzene rings is 44.16 (5)°, smaller than in the previously reported polymorph [56.3 (2)°]. As a result of the steric hinderance of the nitro groups, hydrogen bonding is limited intramolecularly. The dihedral angles between the phenyl rings and their attached nitro groups are 18.97 (6) and 17.71 (5)° at the 2-position, and 18.52 (6) and 32.41 (6)° at the 4-position.

Ethyl (E)-2-cyano-3-(4-methyl-phen-yl)acrylate: a second monoclinic polymorph.

Project description:The title compound, C13H13NO2, was previously described in space group P21/c by He et al. [Acta Cryst. (1993), C49, 2000-2002]. The ethyl group is disordered over two sets of sites in a 0.615?(10):0.385?(10) ratio. The C-O-C-C torsion angles containing the ethyl group are -111.6?(10) and 177.9?(7)°, while in the previously reported polymorph, the torsion angle is -167.3?(2)°. The molecules pack to form a three-dimensional structure in the ABAB style along the c-axis direction in the title compound, but parallel to the a-axis direction in the reported polymorph.

Crystal structure of a new monoclinic polymorph of N-(4-methyl-phen-yl)-3-nitro-pyridin-2-amine.

Project description:The title compound, C12H11N3O2, is a second monoclinic polymorph (P21, with Z' = 4) of the previously reported monoclinic (P21/c, with Z' = 2) form [Akhmad Aznan et al. (2010 ▶). Acta Cryst. E66, o2400]. Four independent mol-ecules comprise the asymmetric unit, which have the common features of a syn disposition of the pyridine N atom and the toluene ring, and an intra-molecular amine-nitro N-H⋯O hydrogen bond. The differences between mol-ecules relate to the dihedral angles between the rings which range from 2.92 (19) to 26.24 (19)°. The geometry-optimized structure [B3LYP level of theory and 6-311 g+(d,p) basis set] has the same features except that the entire mol-ecule is planar. In the crystal, the three-dimensional architecture is consolidated by a combination of C-H⋯O, C-H⋯π, nitro-N-O⋯π and π-π inter-actions [inter-centroid distances = 3.649 (2)-3.916 (2) Å].

A monoclinic polymorph of N-(3-chloro-phen-yl)benzamide.

Project description:The title compound, C(13)H(10)ClNO, (I), is a polymorph of the structure, (II), first reported by Gowda et al. [Acta Cryst. (2008), E64, o462]. In the original report, the compound crystallized in the ortho-rhom-bic space group Pbca (Z = 8), whereas the structure reported here is monoclinic P21/c (Z = 4). The principal difference between the two forms lies in the relative orientations of the phenyl and benzene rings [dihedral angle = 8.90 (13)° for (I) and 61.0 (1)° for (II)]. The inclination of the amide -CONH- units to the benzoyl ring is more similar [15.8 (7)° for (I) and 18.2 (2)° for (II)]. In both forms, the N-H bonds are anti to the 3-chloro substituents of the aniline rings. In the crystal, inter-molecular N-H⋯O hydrogen bonds form C(4) chains along c. These chains are bolstered by weak C-H⋯O inter-actions that generate R(2) (1)(6) and R(2) (1)(7) ring motifs.

A second monoclinic polymorph of N-(pyrazin-2-yl)aniline.

Project description:The two aromatic rings in the title compound, C(10)H(9)N(3), are aligned at 23.4 (1)° and the bridging C-N-C angle is 128.9 (1)°. In the crystal structure, intermolecular N-H⋯N hydrogen bonds result in a chain motif, the repeat distance of which is half the b axial length of 8.8851 (3) Å.

A second monoclinic polymorph of {2,6-bis[(2,4,5-trifluoro-phen-yl)imino-meth-yl]pyridine-κN,N',N''}dichloridonickel(II).

Project description:The asymmetric unit of the title compound, [NiCl(2)(C(19)H(9)F(6)N(3))], contains one half-mol-ecule residing on a crystallographic twofold rotation axis. The title compound crystallizes in space group C2/c while the previously reported polymorph was reported in P2(1)/c [Baldovino-Pantaleón et al. (2006 ▶). Adv. Synth. Catal.348, 236-242]. The Ni(2+) ion exhibits a penta-coordinate distorted trigonal-bipyramidal NiCl(2)N(3) geometry, with two Cl atoms in the equatorial plane. In the crystal, mol-ecules are linked by inter-molecular C-F⋯π [F⋯centroid = 2.9676 (14) Å] inter-actions.

1,3-Bis(2-chloro-phen-yl)thio-urea: a monoclinic polymorph.

Project description:The title compound, C(13)H(10)Cl(2)N(2)S, represents a monoclinic polymorph of the previously reported ortho-rhom-bic form [Ramnathan et al. (1996 ▶). Acta Cryst. C52, 134-136]. The mol-ecule is twisted with the dihedral angle between the benzene rings being 55.37 (7)°. The N-H atoms are syn to each other, which contrasts their anti disposition in the ortho-rhom-bic form. In the crystal, mol-ecules assemble into zigzag chains along the c axis via N-H⋯S hydrogen bonds. Chains are connected into layers via C-H⋯Cl inter-actions, and these stack along the a axis.

Second monoclinic polymorph of 4-[(1H-benzimidazol-1-yl)meth-yl]benzoic acid.

Project description:Recently, we reported the first monoclinic [Kuai & Cheng (2011). Acta Cryst., E67, o2787] and the ortho-rhom-bic polymorph [Kuai & Cheng (2011). Acta Cryst., E67, o3014] of the title compound, C(15)H(12)N(2)O(2). Another monoclinic polymorph was obtained accidentally by the hydro-thermal reaction of the title compound with manganese chloride in the presence of potassium hydroxide at 413 K. The asymmetric unit consists of four independent mol-ecules. In the crystal, O-H⋯N hydrogen bonds link the independent mol-ecules into four separate chains parallel to the b axis.

1-Nitro-4-(4-nitro-phen-oxy)benzene: a second monoclinic polymorph.

Project description:In the title compound, C12H8N2O5, the aromatic rings are inclined to one another by 56.14 (7)°. The nitro groups are inclined by to the benzene rings to which they are attached by 3.86 (17) and 9.65 (15)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming a three-dimensional structure. The title compound is a new monoclinic polymorph, crystallizing in space group P21/c. The first polymorph crystallized in space group C2/c and the mol-ecule possesses twofold rotation symmetry. Two low-temperature structures of this polymorph (150 K and 100 K, respectively) have been reported [Meciarova et al. (2004). Private Communication (refcode IXOGAD). CCDC, Cambridge, England, and Dey & Desiraju (2005). Chem. Commun. pp. 2486-2488].
