| Abstract: Oxidation process of Co[(C6H11O)2PS2]2 and substitute-reduction reaction of Co[(C6H11O)2PS2]3 with pyridine have been studied by spectrophotometric methods, respectively. The equilibrium constant was found to be K=0.63±0.02(mol·dm-3)-3. The crystal structure of Co[(C6H11O)2PS2]2·2Py has been determined by X-ray diff- raction method. The crystal belongs to triclinic system, space group P1, with cell parameters: a=6.944(2)?,b=9.277(3)?,c=15.981(6)?,α=91.79(3)°,β=99.55(3)°,γ=94.44(3)°,V=1011.2(6)?3,Z=2,Mr=803.94,Dc=1.320Mg·m-3,F(000)=425,μ=0.747mm-1,final R=0.0700 and wR=0.1988 for 3626 re-flections with I≥2σ(I). The cobalt atom in the title complex has a octahedral geometry with four Co-S bonds and two Co-N bonds. The central atom P is tetrahedrally surrounded by two sulphur atoms and two oxygen atoms in the dicyclohexyldithiophosphate ligand. The six carbon atoms of cyclohexyl take the chair conformation. |
