Abstract
A new mixed-ligand copper(II) complex of 1,10-phenanthroline (phen) and benzoate ligands having the general formula [Cu(phen)(C6H5CO2)2] is prepared and its crystal structure is determined by X-ray crystallography. The complex exists in the monomeric form; the coordination environment around the copper(II) ion is square planar, with the pair of monodentate benzoate ligands being in a cis disposition. In the crystal, the molecules are linked into [001] chains by weak C-H⋯O interactions; no aromatic π-π stacking occurs.
