Abstract
- The effect of chalcogen bonding interaction led to the interesting crystal packing and coordination geometry of copper(II) in novel organic-inorganic hybrids. The reactions of organic bridging ligands 1,2,5- benzothiadiazole (btd) and 1,2,5-benzoselenazadiazole (bsed) with CuCl<subscript>2</subscript> and CuBr<subscript>2</subscript> by slow diffusion of two miscible solvents afforded three isomorphic 2D-network polymers, [CuCl<subscript>2</subscript>(btd)]<subscript>n</subscript> (1), [CuBr<subscript>2</subscript>(btd)]<subscript>n</subscript> (2), and [CuCl<subscript>2</subscript>(bsed)]<subscript>n</subscript> (3), and one molecular hybrid, CuBr<subscript>2</subscript>(bsed)<subscript>2</subscript> (4). The crystal structures of these novel hybrids were determined by single X-ray crystallography. The three isomorphic hybrids consist of 2-D sheets in which [Cu(µ-X)<subscript>2</subscript>]<subscript>n</subscript> infinite linear chains running along the a axis are linked through N-coordinated molecules of btd and bsed along the b axis. On the other hand, the crystal packing of 4 is strongly influenced by the presence of the [Se...N]<subscript>2</subscript> supramolecular synthon and Se···Br short interactions, all based on chalcogen bonding, that link the dimeric complex molecules into two-dimensional arrays parallel to the ac plane.
