Synthesis of [SCo3(CO)7(S2COMe)] and the structure of its PPh3 derivative

Summary The title compound has been prepared in reasonable yield by reaction of a methanolic solution of CoCl₂ and MeOCS₂K with CO. I.r. spectra have been analyzed both in the C-O stretching region and in the region of the main vibrations of the xanthate ligand: an explanation of the appearance of only 4 out of 7 i.r.-active (CO) modes is proposed. The structure of the triphenylphosphine derivative has been solved by x-ray diffraction analysis: [SCo₃(CO)₆(PPh₃)(S₂COMe)] crystallizes in the triclinic space group P¯1, witha = 10.710(3),b = 10.199(3) andc = 16.208(4) Å, = 113.57(2)°, = 98.14(2)°, = 104.32(2)°, Z = 2, (MoK) = 0.7107 Å. The final R value is 0.045 [4461 reflections with F > 6 (F)]. The molecule is formed by an SCo₃ cluster, in which each Co atom coordinates two CO groups. The chelating xanthate ligand is equatorially bonded to two cobalt atoms forming a nonplanar pentaatomic ring; the phosphine is equatorially bonded to the other cobalt atom.
