Abstract

The title compound, [Cu(C4H2O4)(C12H12N2)(H2O)]n, has a neutral polymeric chain structure in which fumarate ligands link the Cu atoms; the chains are then linked together by hydrogen bonds. The unique CuII ion exhibits a distorted octa­hedral coordination geometry defined by three O atoms of two different centrosymmetric fumarate ligands, two N atoms from the chelating dmbpy ligand (dmbpy is 4,4′‐dimethyl‐2,2′‐bipyridine) and one water mol­ecule. The fumarate ligands show two types of coordination modes, viz. bis‐bidentate‐chelating and bis‐mono‐O‐carboxyl­ate bridging.

“…Each Cu II atom has a distorted square-pyramidal environment, being coordinated by two N atoms of the 1,3-diaminopropane ligand and two cis-oxygen atoms from two bridging fumarate dianions in the basal positions Table 2). The geometry of hydrogen bonds are similar to those reported for a variety of copper compounds (Zheng & Xie, 2004;Dong et al, 2006).…”
