Abstract

In the title compound, [Cu2(CHO2)2(C5H4NO)2(C5H5NO)2].1.02CH3CN, the dimeric unit is centrosymmetric, with two bidentate pyridin-2-olate and two bidentate formate syn-syn bridges, and two apical 2-pyridone ligands coordinated through the O atoms. The N atom from the apical 2-pyridone ligand is a donor of a hydrogen bond to the O atom of the bridging pyridinolate ligand of the same complex. The coordination polyhedron of the Cu atom is a distorted square pyramid.
