Crystal Structure and Luminescent Property of a new Three-Dimensional Polymer Based on 3,5-Di(1H-Benzimidazol-1-yl)Pyridine

Abstract

A three-dimensional Cd(II) complex [Cd(L)(BPDC)]-3H₂O (1) (L = 3,5-di(1H-benzimidazol-1-yl)pyridine, H₂BPDC = biphenyl-4,4-dicarboxylic acid) is synthesized and characterized using single crystal X-ray diffraction, IR spectroscopy, and elemental analysis. The single crystal X-ray diffraction analysis reveals that complex 1 is a novel twofold interpenetrating 4-connected net with a (6⁵·8) topology. Moreover, complex 1 exhibits an emission band at 400 nm with an inconspicuous shoulder at 525 nm (λ_ex = 329 nm).
