Abstract:
The asymmetric unit of the title compound, [Cd2(C7H4NO4)4(C6H4N2)4], contains one CdIIatom, two 3-nitrobenzoate (NB) anions and two 3-cyanopyridine (CPy) ligands. The two CPy ligands act as monodentate N(pyridine)-bonding ligands, while the two NB anions act as bidentate ligands through the carboxylate O atoms. The centrosymmetric dinuclear complex is generated by application of inversion symmetry, whereby the CdIIatoms are bridged by the carboxylate O atoms of two symmetry-related NB anions, thus completing the distorted N2O5pentagonal–bipyramidal coordination sphere of each CdIIatom.

Abstract:
The title compound, C30H32N4, was synthesized by the photodimerization oftrans-4-{2-[4-(dimethylamino)phenyl]ethenyl}pyridine in benzene upon irradiation with UV light. This photodimer has a puckered cyclobutane ring with the four aryl substituents in anr-1,t-2,c-3,tconformation. The puckering angle of the cyclobutane ring is 32.22 (7)°, which is the largest among reported tetraaryl-substituted cyclobutanes. In the crystal, the molecules form a hollow, one-dimensional structure extending parallel to thecaxisviatwo different pairs of C—H...π interactions.
