Bis(cinnamato-κO)(1,10-phenanthroline-κ²N,N′)copper(II)

The title mononuclear Cu^II complex, [Cu(C₉H₇O₂)₂(C₁₂H₈N₂)], 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.
