| Abstract: | Two new members of the hexanuclear series Co6S8(PR3)6]
n+, complexes Co6S8(PMe2Ph)6](ClO4) (1) and Co6S8P(OMe)3
6] (2), have been synthesizes and characterized by X-ray diffraction analyses. Their formation process was postulated to go through trinuclear  3--S bridged moieties. The structural characteristics of the M6E8P6 skeleton of a whole series of M6E8(PR3)6]
n+ (M=Co, Cr, Fe, Mo; E=S, Se, Te) complexes are presented in terms of atomic distances and core volumes. |
