The structure of [Cu(CH3COO)2(4-aminopyridine)2(H2O)] was X-ray studied. Heptacoordinated copper atoms of [Cu(CH3COO)2(4-aminopyridine)2(H2O)] complex are consistent with bond valence sum model based on orbital metal-ligand interaction. Equatorial plane of deformed tetragonal bipyramid as copper coordination polyhedron is formed by atoms O of carboxylato ligands and water molecule. Two N atoms of 4-aminopyridine molecules occupy the axial sites. Each copper atom is semicoordinated by two atoms O from two carboxylato chelates. The lengths of two semicoordinated Cu...O bonds are 3.041(2)A (twice). Seven-coordinated copper atom of the studied compound and Cu(oxalato)(H2O) (4-aminopyridine)2 is consistent with the bond valence sum model.
