Mixed pnicogen and thiolato mononuclear cobalt complexes, Co(SR) 2(PBu n 3) 2 [R = Ph ( 1); R = Stolyl- p ( 2)] and Co(mpo) 2L [L = PBu n 3 ( 3); L = Py ( 4)], have been synthesized and studied spectroscopically. The complexes 1 and 2 are tetrahedral, as determined by magnetic susceptibility studies. The structures of 3 and 4 were determined by X-ray diffraction. The cobalt(II) ions in both 3 and 4 are in a square-pyramidal environment with the two trans-oriented mpo ligands in the basal plane and the pnicogen group in the axial position.
