Bottom Line: The disordered H atom is shared between the carboxyl-ate groups of adjacent quinaldic acid mol-ecules.Such hydrogen bonds delineate zigzag chains that run along the c axis.The structure is very similar to that of the Mn(II) analog.

ABSTRACT
The crystal structure of the title compound, [Cu(C(10)H(6)NO(2))(C(7)H(5)O(2))(C(10)H(7)NO(2))], contains copper(II) ions five-coordinated in a distorted trigonal-bipyramidal environment. The equatorial plane is occupied by three O atoms, one from the carboxyl-ate group of the benzoate ion considered as occupying a single coordination site, the other two from two carboxyl-ate groups of the quinaldic acid and quinaldate ligands. The axial positions are occupied by the N atoms of the quinoline ring system. The metal ion lies on a twofold axis that bisects the benzoate ion. The quinaldate and quinaldic acid ligands are equivalent by symmetry, and the carboxyl-ate/carboxyl groups are disordered. The disordered H atom is shared between the carboxyl-ate groups of adjacent quinaldic acid mol-ecules. Such hydrogen bonds delineate zigzag chains that run along the c axis. The structure is very similar to that of the Mn(II) analog.
