| Abstract | ||
| Cobalt(II), nickel(II), copper(II), zinc(II) and cadmium(II) complexes of the type [M2L (OH)2(H2O)4] (where M = Co(II), Ni(II), Cu(II), Zn(II) or Cd(II); L=2 , 3 -butanedione;while = deprotonated salicylic acid) have been synthesized by 2:1:1 molar reactions of metal chlorides with 2,3-butanedione and salicylic acid. The resulting complexes have been characterized by the metal content measurements, molar conductance measurements ,infrared , electronic spectra and magnetic moment measurements. The complexes are non-electrolytes as is evident from low values of their molar conductance. The infrared spectral studies indicate that the two ligands behave as bidentate chelating ligands. Also the IR studies show that the water molecules are coordinated in all the complexes and the metal centres are bridged by OH groups. The different studies reveal dinuclear nature of the complexes and the two metal atoms are hexacoordinated with octahedral geometry. | ||
