Resumen
In the present work 2-formylpyridine-para-chloro-phenyl hydrazone (H2FopCIPh) and 2-formylpyridine-para-nitro-phenyl hydrazone (H2FopNO(2)Ph) were obtained, as well as their copper(II) and zinc(II) complexes [Cu(H2FopClPh)Cl(2)] (1), [Cu(2FopNO(2)Ph)Cl] (2), [Zn(H2FopClPh)Cl(2)] (3) and [Zn(H2FopNO(2)Ph)Cl(2)] (4). Upon re-crystallization in DMSO:acetone conversion of 2 into [Cu(2FopNO(2)Ph)Cl(DMSO)] (2a) and of 4 into [Zn(2FopNO(2)Ph)Cl(DMSO)] (4a) occurred. The crystal structures of 1, 2a, 3 and 4a were determined. (C) 2009 Elsevier Ltd. All rights reserved.
