title: Four- and five-coordinate copper(II) complexes with N-(4,4-diphenyl-5-oxo-4,5-dihydro-1H-imidazol-2-yl)glycine.
abstract: The two title mononuclear compounds are four-coordinate bis[N-(5-oxo-4,4-diphenyl-4,5-dihydro-1H-imidazolidin-2-ylidene)glycinato]copper(II) dimethylformamide disolvate, [Cu(C(17)H(14)N(3)O(3))(2)].2C(3)H(7)NO, (I), and five-coordinate aquabis[N-(5-oxo-4,4-diphenyl-4,5-dihydro-1H-imidazolidin-2-ylidene)glycinato]copper(II) dimethylformamide disolvate, [Cu(C(17)H(14)N(3)O(3))(2)(H(2)O)].2C(3)H(7)NO, (II). In (I), the Cu(II) ion lies on an inversion centre with one-half of the complex molecule in the asymmetric unit, while in (II) there are two independent ligand molecules in the asymmetric unit, with the Cu(II) ion and coordinated water molecule located on a general position. In both crystal structures, the complex molecules assemble in ribbons via N-H...O hydrogen-bond networks.
