The Complex Co〔S 2P(O- i -C 3H 7) 2〕 3 was synthesized through the reaction of Co 2(CO) 8 with the ligand (C 3H 7- i -O) 2P(S)S-SP(S)(O- i -C 3H 7) 2,and its crystal structure was determined by X-ray four -cycle diffraction method.The crystal belongs to triclinic,space group Pi,crystal cell parameters:a=9 009(2),b=10 437(2),c=18 858(4)?,α=80 99(3),β=88 55(3),γ=82 01(3)°,V=1734 3(6)? 3,Z=2,Mr=698 7,Dc=1 338g·cm -3 ,μ=1 022mm -1 ,F(000)=732,R=0 0342,Rw=0 0812.The structural analysis showed that six sulfur atoms from three ligands 〔S 2P(O- i -C 3H 7) 2〕 coordinate with a cobalt atom,CoS 6 framework in molecular stucture approximately octahedral.The complex was also characterized by IR? 1H NMR? 31 P NMR and MS.
