Bis(cinnamato-κO)(1,10-phenanthroline-κ(2) N,N′)copper(II)

The title mononuclear Cu(II) complex, [Cu(C(9)H(7)O(2))(2)(C(12)H(8)N(2))], is comprised of a Cu(II) cation, two cinnamate (L (−)) ligands and a 1,10-phenanthroline (phen) ligand. The Cu(II) atom and phen ligand lie on a twofold rotation axis. The Cu(II) atom is coordinated by two O atoms from two carboxyl­ate groups of two (L (−)) ligands and two N atoms from one phen ligand, exhibiting a distorted square-planar geometry. In the crystal, mol­ecules are assembled into supra­molecular chains parallel to the c axis through weak C—H⋯O hydrogen bonds involving the phen and cinnamate ligands.
