(2,2′-Bipyridine-κ(2) N,N′)bis­(4-formyl­benzoato-κO (1))copper(II)

The title mononuclear Cu(II) complex, [Cu(C(8)H(5)O(3))(2)(C(10)H(8)N(2))], is comprised of a Cu(II) cation, two 4-formyl­benzoate (L (−)) ligands and a 2,2′-bipyridine (bipy) ligand. The Cu(II) ion and bipy ligand lie on a crystallographic twofold rotation axis; the Cu(II) ion is coordinated by two N atoms from one bipy ligand and two O atoms from two different carboxyl­ate groups of two L (−) ligands, exhibiting effectively a distorted square-planar geometry. The complex mol­ecules are inter­linked to generate two-dimensional supra­molecular layers in the ab plane, formed by C—H⋯O hydrogen bonds, where the O acceptor is the O atom from the carboxyl­ate group not involved in coordination to the Cu(II) ion. The two-dimensional layers are stacked in a sequence via C—H⋯O hydrogen-bonding inter­actions where the formyl O atom acts as acceptor.
