Chelate complexes of copper(II) and nickel(II) with anions of nitroxide radical ethyl-2-(1-oxyl-2,2,5,5-tetramethylimidazolidin-4-yliden)-3-oxopropanoate (HL) are synthesized. The compounds have molecular structure and zero magnetic dimensionality. CuL(2) crystallizes as two polymorphs having mononuclear structure. Ni(2)L(4) forms dimeric molecules by virtue of the bridging function of the aldehyde oxygen atoms. Magnetic properties of Ni(2)L(4) are determined by antiferromagnetic exchange interactions between the Ni(II) ions (-48(1) K) propagated through the oxygen bridges.
