BIS[(4-AMINO-2-METHYL-5-PYRIMIDINYL-METHYLTHIO)ACETATO] COBALT(II), NICKEL(II) AND COPPER(II) COMPLEXES

Abstract
Cobalt(II) nickel(II) and copper(II) complexes of (4-amino-2-methyl-5-pyrimidinyl methylthio) acetate have been synthesized and characterised. All the complexes are paramagnetic with coordination involving a sulphur atom and the oxygen atom of the carboxylate group. Cobalt(II) is four-coordinate, nickel(II) is six-coordinate while copper(II) is five-coordinate. Although the complexes are non-electrolytes in DMF and DMSO. they are found to be amphoteric.
