چکیده
The title compound, C30H32N4, was synthesized by the photodimerization of trans-4-{2-[4-(di-methyl-amino)-phen-yl]ethen-yl}pyridine in benzene upon irradiation with UV light. This photodimer has a puckered cyclo-butane ring with the four aryl substituents in an r-1,t-2,c-3,t conformation. The puckering angle of the cyclo-butane ring is 32.22 (7)°, which is the largest among reported tetra-aryl-substituted cyclo-butanes. In the crystal, the mol-ecules form a hollow, one-dimensional structure extending parallel to the c axis via two different pairs of C-H⋯π inter-actions.

In the title compound, [Mn(C6H6O4)(C12H12N2)(H2O)] n , the cyclo-butane-1,1-di-carboxyl-ate (cbdc) ligands bridge three Mn(II) ions, forming layers parallel to the ac plane. These layers are additionally connected by 1,2-bis-(pyridin-4-yl)ethane ligands to form a three-dimensional polymeric framework. An inversion centre is located at the mid-point of the central C-C bond of the 1,2-bis-(pyridi...
