  Tetranuclear copper(II) complexes with polydentate hydrazone ligands: synthesis and X-ray structure

  摘要：

  The synthesis and X-ray crystal structure of two copper(II) complexes, [Cu2(dappc)(OH2)3]2-[Cu2(dappc)(OH2)2(ClO4)6.2H2O (I) (H2dappc = 2,6-diacetylpyridine bis(2-pyridinecarbonylhydrazone)) and [Cu2(dapip')Br]2.2H2O, (II) (H3dapip' = 2,6-diacetylpyridine 2-pyridinecarbonylhydrazone 2-(2'-pyridine carbonylhydrazono)phenylacetohydrazone) are reported. The interest of both structures pertains mainly to their tetranuclear nature with dimeric units related by an imposed center of symmetry. The structure of compound I is built up from two different complex cations, ClO4- anions and uncoordinated H2O molecules, while that of compound II consists of neutral complex molecules and solvating H2O molecules. During the formation of the latter complex the original H4dapip ligand (H4dapip = 2,6-diacetylpyridine bis[2-(2'-pyridinecarbonylhydrazono)phenylacetohydrazone] has undergone a modification through a hydrolysis process, resulting in partial cleavage of one arm to give H3dapip'.

• Syntheses and structures of four antimony complexes with planar tridentate pyridine ligands

  The syntheses and structures of four antimony chloride complexes with tridentate N,N,O Schiff base ligands are reported. The tridentate ligands derived from 2-acetylpyridine and various acid hydrazides all lost a proton upon coordination. The ligand was either negative or zwitterionic depending on the acid hydrazide. The complexes are water soluble although a hydrolysis reaction can occur. The appearance of the mu-dichloro-mu -oxo-tetrachlorodiantimonate(III) anion in one of the complexes was unexpected but appears to be related to the temperatures used in the synthesis. The variation in the distances in the various complexes and the anion are discussed using bond valence sum calculations. (c) 2007 Elsevier B.V. All rights reserved.
