The title compound has been synthesized by reaction system (NH 4) 3VS 4/CoCl 2(PPh 3) 2/NEt 4Cl in CH 2Cl 2 and structurally determined by single crystal X ray diffraction. Crystallographic data: cubic space group Pa3, formula C 26 H 35 NCl 3CoP, M r= 557.84, a=17.807(7) , V = 5646.4 3, Z=8, D c= 1.31 g/cm 3, F(000) = 2328, μ (Mo Kα ) = 9.6 cm -1 , R = 0.062, R w = 0.067. Its molecular structure possesses crystallographic 3 fold symmetry axis. The Co(II) atom has a tetrahedral coordination with bond angle Cl-Co-Cl( 113.4(2)° ) greater than Cl-Co-P( 105.2(2)° ). The electronic spectrum and magnetic moments dependent on temperatures have also been discussed.
