3-Iodo-1H-pyrazolo-[3,4-b]pyridine.

ABSTRACT: The title compound, C6H4IN3, is essentially planar, with a dihedral angle of 0.82?(3)° between the planes of the pyridine and pyrazole rings. In the crystal, pairs of mol-ecules are connected into inversion dimers through N-H?N hydrogen bonds. C-I?N halogen bonds link the dimers into zigzag chains parallel to the b-axis direction. The packing also features ?-? stacking inter-actions along (110) with inter-planar distances of 3.292?(1) and 3.343?(1)?Å, and centroid-centroid distances of 3.308?(1) and 3.430?(1)?Å.

2-(5-Isopropyl-3-methyl-sulfanyl-1-benzofuran-2-yl)acetic acid.

Project description:There are two mol-ecules in the asymmetric unit of the title compound, C(14)H(16)O(3)S. In the crystal structure, the carboxyl groups are involved in inter-molecular O-H?O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. These dimers are further packed into stacks along the a axis by aromatic ?-? inter-actions between the furan rings of adjacent mol-ecules [centroid-centroid distance = 3.430?(4)?Å] and by additional C-H?? and C-H?O inter-actions.

2-(4-Bromo-phen-yl)-N-[3-(1H-imidazol-1-yl)prop-yl]quinazolin-4-amine.

Project description:In the title compound, C(20)H(18)BrN(5), the bromo-phenyl-substituted quinazoline unit is essentially planar [maximum deviation = 0.098?(3)?Å] and makes a dihedral angle of 56.04?(14)° with the imidazole ring. In the crystal, mol-ecules are associated by pairs of N-H?N hydrogen bonds to form inversion dimers. All the quinazoline planar systems are oriented almost perpendicular to the [110] direction, making ?-? inter-actions possible between adjacent dimers [centroid-centroid distances = 3.7674?(16) and 3.7612?(17)?Å]. There are also a number of C-H?? inter-actions present. The crystal is a nonmerohedral twin, with a minor twin fraction of 0.47.

10-Methyl-isoalloxazine 5-oxide from synchrotron powder diffraction data.

Project description:THE TITLE COMPOUND [SYSTEMATIC NAME: 10-methyl-benzo[g]pteridine-2,4(3H,10H)-dione 5-oxide], C(11)H(8)N(4)O(3), consists of a large rigid isoalloxazine group which is approximately planar (r.m.s. deviation = 0.037?Å). In the crystal, inter-molecular N-H?O hydrogen bonds link the mol-ecules into centrosymmetric dimers. Dimers related by translation along the c axis form stacks through ?-? inter-actions [centroid-centroid distances = 3.560?(5) and 3.542?(5)?Å]. Weak inter-molecular C-H?O inter-actions further consolidate the crystal packing.

N-(2-Hydroxy-ethyl)-1,8-naphthalimide.

Project description:In the mol-ecule of the title compound, C(14)H(11)NO(3), the naphthalimide ring system is nearly planar (r.m.s. deviation 0.0139?Å).

(2E)-2-[2-(4-Chloro-phen-yl)hydrazin-1-yl-idene]-4,4,4-trifluoro-3-oxobutanal.

Project description:The title compound, C(10)H(6)ClF(3)N(2)O(2), was synthesized by coupling 4-dimethyl-amino-1,1,1-trifluoro-but-3-en-2-one with 4-chloro-benzene-diazo-nium chloride. It crystallizes with two mol-ecules in the asymmetric unit, which form two similar centrosymmetric dimers via hydrogen bonds. Extensive electron delocalization and intra-molecular N-H?O hydrogen bonds are responsible for a planar conformation of the mol-ecules (maximum deviations = 0.010 and -0.015?Å for the two molecules). In addition to hydrogen bonds, ?-? stacking inter-actions with centroid-centroid distances of 3.604?(2) and 3.583?(2)?Å contribute to the stability of the crystal structure.

Crystal structure of (5-methyl-imidazo[1,2-a]pyridin-2-yl)methanol.

Project description:In the title compound, C9H10N2O, the imidazo[1,2-a]pyridine moiety is approximately planar (r.m.s. deviation = 0.024?Å). The methanol group is nearly perpendicular to its mean plane as indicated by the C-C-C-O and N-C-C-O torsion angles of 80.04?(16) and -96.30?(17)°, respectively. In the crystal, mol-ecules are linked by O-H?N hydrogen bonds, forming inversion dimers with an R (2) 2(10) ring motif. The dimers are liked via C-H?O hydrogen bonds, enclosing R (2) 2(10) ring motifs and forming ribbons along [201]. The ribbons are linked via a number of ?-? inter-actions [centroid-centroid distances vary from 3.4819?(8) to 3.7212?(8)?Å], forming a three-dimensional structure.

7-(4-Meth-oxy-phen-yl)-4,9-dimethyl-N-(4-methyl-phen-yl)-5,12-diaza-tetra-phen-6-amine.

Project description:In the title compound, C(32)H(27)N(3)O, the fused tetra-cycilc ring system is essentially planar [r.m.s. deviation = 0.07?(7)?Å]. An intra-molecular N-H??(arene) inter-action and a weak intra-molecular C-H?N hydrogen bond may influence the mol-ecular conformation. In the crystal, weak inter-molecular C-H?N hydrogen bonds link the mol-ecules into centrosymmetric dimers, forming R(2) (2)(14) motifs. In addition, weak ?-? stacking inter-actions with centroid-centroid distances in the range 3.578?(1)-3.739?(1)?Å provide further stabilization.
