Crystal structure of 3-(1H-benzimidazol-2-yl)propano­ato-κN33-(1H-benzimid­azol-2-yl)propanoic acid-κN3copper(I)

摘要

In the title compound, [Cu(C10H9N2O2)(C10H10N2O2)], the Cu^I ion is situated at a crystallographic centre of inversion and is coordinated in a linear environment by two benzimidazole N atoms from two symmetry-related 2-propanoic-1H-benzimidazole ligands. The ligands are disordered in a sense that statistically one of the carb­oxy­lic acid groups in each mol­ecule is deprotonated. In the crystal, O—H⋯O hydrogen bonds link the mol­ecules into chains along the a-axis direction. These chains are additionally linked into infinite two-dimensional networks in the ab plane by N—H⋯O hydrogen bonds.
