Two types of complexes of 2-phenyl-4-(piperidyl-1)-pyrido[2,3-a]anthraquinone (L) with transition metals were isolated from neutral acetonitrile and acidified acetonitrile and ethanol solutions and characterized. Metal complexes synthesized at pH = 7 had the composition MCl2L center dot(CH3CN)(n) (M = Cu, Co, Ni). The complexes (HL)(2)[CU2Cl6] (I), (HL)(2)[CoCl4] (II), (HL)(2)[Zn(NO3)(4)] (III) were obtained at pH = 1-2. The molecular and crystal structure ofcomplex III was determined. Some spectral parameters ofL and its complexes were measured.
