Crystal structure of (3,5-dimethyl-1H-pyrrol-2-yl)di-phenyl-phosphine oxide.

ABSTRACT: The title compound, C₁₈H₁₈NOP, was obtained during a search for new P,N-containing ligands with the potential to generate precatalysts with chromium(III) for selective ethyl-ene oligomerization. In the crystal, mutual pairs of N-H⋯O=P hydrogen bonds link two mol-ecules into a dimer with individual mol-ecules related by a twofold rotation axis. The P=O bond length of 1.4740 (15) Å is not elongated although the O atom is involved in hydrogen bonding. The crystal structure is further stabilized by van der Waals inter-actions between the dimers, linking the mol-ecules into a three-dimensional network structure.

Crystal structure of dimethyl 3,4,5,6-tetra-phenyl-cyclo-hexa-3,5-diene-1,2-di-carboxyl-ate.

Project description:In the title compound, C34H28O4, the cyclo-hexa-diene ring has a screw-boat conformation with a torsion angle between the double bonds being on average ca 15° [15.2 (3) and -15.3 (3) in the two independent mol-ecules]. All four phenyl rings in both mol-ecules are arranged in a propeller-like conformation. The two mol-ecules exhibit S,R- and R,S- chirality, respectively, and are connected via C-H⋯O inter-molecular inter-actions. In turn, these weakly bound dimers form the mol-ecular crystal.

Project description:In an effort to discover novel and potential boron-dipyrromethene (BODIPY) dyes, the title compound, C(19)H(18)BF(2)N(3)O(2), was prepared from 2,4-dimethyl-pyrrole, 4-nitro-benzaldehyde and BF(3)·Et(2)O in a one-pot reaction. There are two independent mol-ecules, A and B, in the asymmetric unit in which the dihedral angles between the benzene ring and boron-dipyrromethene mean plane have significantly different values [82.71 (8)° for mol-ecule A and 73.16 (8)° for mol-ecule B]. Inter-molecular C-H⋯π inter-actions help to stabilize the crystal structure.

Crystal structures of 4-chloro-phenyl N-(3,5-di-nitro-phen-yl)carbamate and phenyl N-(3,5-di-nitro-phen-yl)carbamate.

Project description:The title compounds, C13H8ClN3O6, (I), and C13H9N3O6, (II), differ in the orientation of the two aromatic rings. In (I), they are essentially coplanar, making a dihedral angle of 8.2 (1)°, while in (II), they are inclined to one another by 76.2 (1)°. The two nitro groups are essentially coplanar with the attached benzene rings, as indicated by the dihedral angles of 1.4 (2) and 2.3 (2)° in (I), and 4.96 (18) and 5.4 (2)° in (II). The carbamate group is twisted slightly from the attached benzene ring, with a C-N-C-O torsion angle of -170.17 (15)° for (I) and 168.91 (13)° for (II). In the crystals of of both compounds, mol-ecules are linked via N-H⋯O hydrogen bonds, forming chains propagating along [010]. In (I), C-H⋯O hydrogen bonds also link mol-ecules within the chains. The crystal packing in (I) also features a very weak π-π inter-action [centroid-centroid distance = 3.7519 (9) Å].

Project description:The title mol-ecule, C20H20B2F4N4, assumes a planar conformation with all atoms apart from the F atoms lying on the symmetry plane. Each boron atom is four-coordinated by two fluorine atoms, a pyrrole N atom and an imine N atom. Both imine CH=N groups adopt a trans conformation. In the crystal, the mol-ecules self-assemble into a pillar structure through C-H⋯F hydrogen bonds and π-π inter-actions. The UV-vis spectrum and fluorescence spectra of the title compound are also reported.

Crystal structure of phenyl N-(3,5-di-methyl-phenyl)carbamate.

Project description:The asymmetric unit of the title compound, C15H15NO2, contains two independent mol-ecules (A and B). The di-methyl-phenyl ring, the phenyl ring and the central carbamate N-C(=O)-O group are not coplanar. In mol-ecule A, the di-methyl-phenyl and phenyl rings are inclined to the carbamate group mean plane by 27.71 (13) and 71.70 (4)°, respectively, and to one another by 84.53 (13)°. The corresponding dihedral angles in mol-ecule B are 34.33 (11), 66.32 (13) and 85.48 (12)°, respectively. In the crystal, the A and B mol-ecules are arranged alternately linked through N-H⋯O(carbon-yl) hydrogen bonds, forming -A-B-A-B- chains, which extend along [100]. Within the chains and linking neighbouring chains there are C-H⋯π inter-actions present, forming columns along the a-axis direction. The columns are linked by offset π-π stacking inter-actions, forming a three-dimensional network [shortest centroid-centroid distance = 3.606 (1) Å].

Crystal structure of 3,5-di-methyl-phenyl 2-nitro-benzene-sulfonate.

Project description:The title compound, C14H13NO5S, was synthesized via a nucleophilic substitution reaction between 3,5-di-methyl-phenol and 2-nitro-benzene-sulfonyl chloride. The aromatic rings attached to the SO3 group are oriented in a gauche fashion around the ester S-O bond, with a C-S-O-C torsion angle of 84.68 (11)°. The mol-ecules form centrosymmetric dimers via π-π stacking inter-actions between 3,5-di-methyl-phenyl groups (centroid-centroid distance = 3.709 Å). An inter-molecular S=O⋯N inter-action between the sulfonyl and nitro groups, with an O⋯N distance of 2.9840 (18) Å, organizes the dimers into columns extending along [011]. These columns are further assembled into (111) layers through C-H⋯O inter-actions.
