The reaction of Cu(ClO4)2·6H2O and Cd(ClO4)2 with di-(2-picolyl)sulfur (dps) leads to the formation of mononuclear complexes [Cu(dps)(H2O)(ClO4)](ClO4) (1) and [Cd(dps)2](ClO4)2 (2). The crystal structure of 1 exhibits a distorted square pyramidal geometry, coordinated by one sulfur and two nitrogen atoms from the dps ligand, one
water molecule and one perchlorate oxygen atom. For 2, the environment around cadmium atom is in a distorted octahedron with four nitrogen and two sulfur atoms from the dps ligand.
Cyclic voltammetric data show that complexes undergo two waves of a one-electron transfer corresponding to M(II)/M(III) and
M(II)/M(I) processes. Spectral and electrochemical behaviors of the complexes are also discussed. 相似文献

Two mononuclear copper(II) complexes [Cu(L)(NO2)](ClO4) (1) and [Cu(L)(MO4)]2· 5H2O (2) (L = 1,3,10, 12,16,19-hexaazatetracyclo[17,3,1,112.16,04.9]tetracosane) have been synthesized and their structures determined. Both compounds show a distorted square-pyramidal geometry with the two secondary and two tertiary amines of the macrocycle and one ligand coordinated at the axial position. Cyclic voltammetry of the complexes gives two one-electron waves corresponding to CuII/CuIII and CuII/CuI processes. The electronic spectra and electrochemical behavior of the complexes are significantly affected by the nature of the organic ligands. 相似文献
