trans-1-Phenylpyrrolidine-2,5-dicarbonitrile
نویسندگان
چکیده
In the title compound, C(12)H(11)N(3), the plane of the phenyl ring and the least-squares plane of the pyrrolidine ring enclose an angle of 14.30 (6)°. The intra-cyclic N atom features a nearly trigonal-planar coordination geometry due to π-inter-actions with the aromatic system. The pyrrolidine ring is present in a twist conformation for which the closest pucker descriptor is (C9)T(C8). Weak inter-molecular C-H⋯N and C-H⋯π contacts occur.

The asymmetric unit of the title compound, C14H22N2O2Si2, contains one half of the mol-ecule, which is completed by inversion symmetry. The cyclo-hexa-2,5-diene ring is exactly planar and reflects the bond-length distribution of a pair of located double bonds [1.3224 (14) Å] and two pairs of single bonds [1.5121 (13) and 1.5073 (14) Å]. The tetra-hedral angle between the sp (3)-C atom and the t...

In the title compound, C14H13NO3, the dihedral angles between the central pyrrolidine ring and the pendant tetra-hydro-furan and phenyl rings are 5.34 (18) and 58.99 (17)°, respectively. The tetra-hydro-furan ring is almost planar (r.m.s. deviation = 0.008 Å). In the crystal, mol-ecules are linked by C-H⋯O inter-actions, generating a three-dimensional network.

In the crystal of the title compound, C16H9BrN2O4·0.5C6H6, the mol-ecules stack in a centrosymmetric unit cell in a 2:1 stoichiometry with co-crystallized benzene solvent mol-ecules and inter-act via various weak inter-actions. This induces a geometry different from that predicted by theory, and is unique among the hemibi-quinones heretofore reported.

The asymmetric unit of the title compound, C10H6N2S2, contains two crystallographically independent but conformationally similar mol-ecules. The fused thio-phene ring cores are almost planar [maximum deviation = 0.027 (3) Å] with the thio-phene rings forming dihedral angles of 0.5 (4)° in one mol-ecule and 1.91 (4)° in the other. The crystal packing is stabilized only by van der Waals inter-act...
