The reaction of Fe3(CO)12 with P(SPh)3 yields the tile compound. C41H30Fe2O5P2S6, Mr = 968. 65, monoclinic, space group, P21/n, a = 14. 449(9), b = 18. 046(11), c=16.871(10)(?), β=98. 76°, V = 4348(?)3, Z = 4, Dc=1. 480g/ cm3, λ(MoKα) = 0. 71073(?) The structure was determined by direct methods and difference Fourier syntheses and refined by full-matrix least-squares procedure to R = 0.084, Rw = 0.144 for 4059 reflections. Fe(1)-Fe(2) = 2. 576(6), Fe(2)-P(2) = 2.194(9)(?). The dihedral angle between the Fe(l)SFe(2) and Fe(1)PFe(2) planes is 81. 9°. The other one (dihedral angle between SFe(1)P and SFe(2)P planes) is 75. 2°.
