Abstract Co 4 ( μ 3 ‐S) 8 (Ph 2 PCH 2 sP(O)Ph 2 ) 6 , MW = 3012.5, space group R 3 , has the hexagonal parameters, a = 26.764 (10), c = 16.979 (10) Å, V = 10532.8 Å 3 , Z = 3. Mo K a radiation, λ = 0.71069 Å, Dc = 1.425 g/cm 3 , μ = 9.94 cm −3 , F (000) = 4650, R = 0.073 and Rw = 0.077 for 1965 observed unique reflections with I > 3σ ( I ). The molecular structure consists of a distorted octahedral Co 4 —core. The Co—Co and Co—S distances fall in the range of 2.805—2.838 and 2.213—2.253 Å, respectively.
