Popis: Three novel copper(II) complexes as condensation derivatives of 2-pyridinecarboxaldehyde, 2-acetylpyridine or 2-quinolinecarboxaldehyde with ethyl hydrazinoacetate hydrochloride were synthesized. X-ray crystal structures of all three complexes were determined. Crystallographic data indicate a common basis of the structures with some major differences. Both pyridine derivatives form complexes of the type [CuCl(2)L] with distorted square-planar geometry around copper(II), but show a decisive difference in the side chain orientation. The quinoline derivative forms a dimeric complex of type [Cu(2)Cl(4)L(2)] with distorted trigonal bipyramidal geometry around copper(II), but a rather short Cu center dot center dot center dot Cu contact, which is reflected in its magnetic properties. All three complexes showed antibacterial activity. (c) 2008 Elsevier B.V. All rights reserved.
