Pentaaqua(1H-benzimidazole-5,6-dicarboxylato-κN3)copper(II) pentahydrate
Abstract
The title compound, [Cu(C9H4N2O4)(H2O)5]·5H2O, contains one crystallographically independent CuII atom and one 1H-benzimidazole-5,6-dicarboxylate (bdc) ligand, along with five coordinated and five uncoordinated water molecules. The CuII atom is six-coordinated by one N atom from the bdc ligand and five O atoms from water molecules, giving an octahedral coordination geometry. Hydrogen bonds link the mononuclear complex and uncoordinated water molecules into a three-dimensional network.
