dc.description.abstract | Starting from Cu(II) and Ni(II) perchlorate and Fe(III) chloride in the presence of 2,6-diacetylpyridine (dap) and semioxamazide (sox), the [Cu(Hdapsox)H2O]ClO4 (I), [Ni(Hdapsox)(MeOH)(2)]ClO4 (II) and [Fe(Hdapsox)Cl-2]. 1/2H(2)O (III) complexes with a singly deprotonated ligand Hdapsox(-) of the acyl hydrazone class (with H(2)dapsox = 2',2'''-(2,6-pyridindiyldiethylidene)dioxamohydrazide) have been obtained and characterized for the first time by a template synthesis. The previously assumed [1] square-pyramidal structure of the Cu(II) complex with an asymmetrical coordination of Hdapsox(-) has been confirmed by a single-crystal X-ray analysis. In II Hdapsox(-) is octahedrally coordinated around a Ni(II) ion, while III is found to be a pentagonal-bipyramidal complex with a symmetrically bonded Hdapsox(-). Causes of a ligand deprotonation occurring in a very acid medium (pH = 0) and of a different coordination pattern in the case of Cu(II), NI(II) and Fe(III) are interpreted by a d(n) configuration and an effective nuclear charge of the central metal ion (crystal field effects).
