The complexes, tetra-mu-[2-(phenylamino)benzoato](O,O')-bis[(ethanol)copper(II)] (1) and di-mu-[2-(phenylamino)benzoato](O,O')-bis[(hydroxo)copper(II)] (2), were synthesized by the reaction of N-phenylanthranilic acid and CuCl2 center dot 2H(2)O in an ethanol water mixture. In complex 1, each Cu(II) atom, which is in a slightly distorted square pyramidal environment, is coordinated equatorially by four N-phenylanthranilate O-atoms and axially by the ethanol O-atoms. In complex 2, [Cu-2(C6H5NHC6H4COO)(2)(OH)(2)], each Cu(II) atom, which is in tetrahedral environment, is coordinated by two N-phenylanthranilate O-atoms and hydroxo ligands. The crystal structure (monoclinic, P21/c space group) of complex 1 comprises a dinuclear [Cu-2(C6H5NHC6H4COO)(4)(CH3CH2OH)(2)] species and the dimer is located on a crystallographic inversion centre. The Cu(II) ions, 2.591(2) apart, are bridged by the carboxylate groups of four N-phenylanthranilate ligands. The complex molecules show three-dimensional supramolecular networks by O-H center dot center dot center dot O, C-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions.
