Synthesis and Crystal Structure of the Cobalt (Ⅱ) Complex with Mixed-Ligand

摘要

The Cobalt (II) Complex constructed with 5-nitroisophthalic acid and 2,2'-bibenzimidazole, [Co(H_2bibim)_2( 5-nipa)] (1), (H_2bibim =2,2'-bibenzimidazole, 5-nipa=5-nitroisophthalic acid) have been synthesized by hydrothermal methods and structurally characterized by elemental analysis, IR and X-ray single crystal diffraction. Complex 1 has six coordinated by two H_2bibim ligands and one 5-nitroisophthalic acid groups that is further connected though intermolecular hydrogen bonds and resulting in a three-dimensional (3D) network.
