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. © 2019, Pleiades Publishing, Ltd.
