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

Abstract

The reaction of NiCl₂·6H₂O or Zn(CH₃CO₂)·2H₂O 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 P2₁/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.
