Polymeric structure of succinatobis(benzimidazole)copper(II) monohydrate

A new complex compound: Cu(C₇H₆N₂)₂(C₄H₄O₄ H₂O] has been synthesized and its crystal structure investigated by single-crystal X-ray methods. The structure was refined by full-matrix least-squares to giveR=0.031 andR _w =0.038 for 1765 intensities above 3(I). The structure consists of polymeric chains Cu(C₇H₆N₂)₂(C₄H₂O₄)] parallel to 110] and ¯110], connected by long Cu-H₂O-Cu bonds along 001]. Succinate ions exhibit antiperiplanar conformation and are only bidentate ligands. Interchain interactions by hydrogen bonds and stacking of aromatic ligands are discussed.
