Synthesis and Crystal Structure of Nickel(II) and Zinc(II) Complexes With O-Propylxanthate and N,N,N,N-Tetramethylethylenediamine

Abstract

The reaction of NiCl(2)6H(2)O or Zn(CH3CO2)2H(2)O with potassium O-propylxanthate (KS2COC3H7) and N, N, N,N-tetramethylethylenediamine (tmeda) affords monomeric complexes of the formula [M(S2COC3H7)(2)(tmeda)] (M = Ni(II) 1; Zn(II) 2). Both complexes are characterized by single crystal X-ray diffraction, elemental analysis, IR spectroscopy. Complexes 1 and 2 crystalize in monoclinic P2(1)/c and I2/a space groups, respectively. Each metal center is ligated by four S atoms from xanthate ligands and two N atoms from tmeda in a distorted octahedral geometry.
