Oxidation process of Co (C 6 H 11 O) 2 PS 2 2 and substitute-reduction reaction of Co C 6 H 11 O) 2 PS 2 3 with pyridine have been studied by spectrophotometery methods, respectively. The equilibrium constant was found to be K = 0.63 ± 0.02 (mol · dm -3) -3. The crystal structure of Co 6 H 11 O) 2 PS 2 2 · 2 Py has been determined by X- ray diff-raction method. The crystal belongs to triclinic system = space groupP1 with cell parameters: a = 6.944 (2) ?, b = 9.277 (3) ?, c = 15.981 ?,? = 91.79 ?,? = 99.55? = 94.44 (3) °, V = 1011.2 (6)? 3, Z = 2, M r = 803.94, D c = 1.320 Mg · m -3, F (000) = 425, μ = 0.747 mm -1 R = 0.0700 and w R = 0.1988 for 3626re-flections with I ≥ 2σ (I). The cobalt atom in the title complex has an octahedral geometry with four Co-S bonds and two Co-N bonds. The central atom P is t etrahedrally surrounded by two sulp hur atoms and two oxygen atoms in the dicyclohexyldithiophosphate liga n d. the six carbon atoms of cyclohexyl take the chair conformation.
