The title compound was obtained by the reaction of (NH4) 3VS4 / CoCl2 (PPh3) 2 / NEt4Cl in CH2 Cl2. The single crystal X-ray structure analysis showed that the crystal belongs to the cubic system with the chemical formula of C2 6 H35 NCl3CoP, space group Is Pa3, Mr = 5 5 7.84, a = 17.80 7 (5), V = 5 6 46 .4 3, Z = 8, Dc = 1.31 g / cm3, F (0 0 0) = 2 32 8, MoKα) = 9.6 cm -1, R = 0.026, Rw = 0.067. The molecular structure of the title compound has crystallographic tertiary axisymmetry, the Co (II) atom is tetrahedrally coordinated, the bond angle Cl-Co-Cl (113.4) is greater than the bond angle Cl-Co-P .twenty two). The electronic spectra and temperature-dependent magnetic susceptibility of the title compound are also discussed
