The acetato-bridged polymeric Schiff base zinc(II) complex [Zn(MENP)(CH3COO)]n (MENP = 2-[2-(methylamino) ethyliminomethyl]-4-nitrophenolate) was synthesized and characterized by elemental analysis, IR and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P21/c with a = 14.054(2), b = 11.167(1), c = 9.323(2) A, β = 92.053(2)°, V = 1462.2(4) A3, Z = 4, R 1 = 0.0420 and wR 2 = 0.1019. The Zn atom is coordinated in a trigonal-bipyramidal manner by one Schiff base ligand and two bridging acetate anions. The adjacent Zn...Zn distance is 4.727(2) A. The [Zn(MENP)] units are linked through the bridging acetate groups, forming chains running along the c axis. The complex shows slight cytotoxic property to both normal and carcinoma cells.

Three mononuclear copper(II) complexes, [Cu(L1)(DMF)]ClO 4 (1), [Cu(L2)(DMSO)]ClO4 (2) and [CuL 3(NCO)] (3) (where HL1 {2-[(2-methylamino-ethylimino)- methyl]-4-nitro-phenol}, HL2 {2-[(2-ethylamino-ethylimino)-methyl]-4- nitro-phenol} and HL3 {2-[(2-(dimethylamino)ethylimino)methyl]-4- nitrophenol} are tridentate Schiff-base ligands), have been synthesized and characterized by elemental analysis, IR and UV-Vis spectroscopy and single-crystal X-ray diffraction studies. All the complexes are square planar. Complex 1 crystallizes in the triclinic space group, P1?, with cell dimensions a = 8.0396(2), b = 9.0892(2), c = 12.9977(3) ?, α = 85.591(1), β = 84.198(1) and γ = 76.423(1), whereas complex 2 crystallizes in the orthorhombic space group, Pbca with cell dimensions a = 8.4615(4), b = 17.2708(11) and c = 25.8517(12) ?. Complex 3 crystallizes in the monoclinic space group, P21/n with cell dimensions a = 6.9550(3), b = 13.2257(7), c = 14.7755(6) ? and β = 102.697(3). Both HL1 and HL2 are capable of forming H bonds due to the presence of H atoms in their amine groups. On the other hand, HL3 cannot form H-bonds. The weak forces like H-bonding, lone paira?π and πa?π interactions lead to various supramolecular architectures in the complexes.
