| Abstract: | In the present work 2-formylpyridine-para-chloro-phenyl hydrazone (H2FopClPh) and 2-formylpyridine-para-nitro-phenyl hydrazone (H2FopNO2Ph) were obtained, as well as their copper(II) and zinc(II) complexes Cu(H2FopClPh)Cl2] (1), Cu(2FopNO2Ph)Cl] (2), Zn(H2FopClPh)Cl2] (3) and Zn(H2FopNO2Ph)Cl2] (4). Upon re-crystallization in DMSO:acetone conversion of 2 into Cu(2FopNO2Ph)Cl(DMSO)] (2a) and of 4 into Zn(2FopNO2Ph)Cl(DMSO)] (4a) occurred. The crystal structures of 1, 2a, 3 and 4a were determined. |
