SYNTHESIS AND STRUCTURE OF THE CLUSTER COMPOUND {[Mo_3(μ_3-S)(μ-S_2)_3(dtp)_3]_2Cl}·FeCl_4, (dtp=S_2P(OC_2H_5)_2)

<正> The title compound, C24H6oCl5O12P6S26FeMo6,Mr = 2369. 00,crystallized in monoclinic,space group P21/n with cell parameters a= 17. 378(9) ,b=19. 752 (6),c=23. 845(A),β=84. 50(4)°,V = 8133. 4A3,Z=4,Z)c=1.931gcm-3,F(000) = 4676. 00. MoKa radiation (λ=0. 71073A),R=0. 070 for 8403 reflections with I≥3σ(I). The structure was solved by direct methods and showed to consist of an anion Fe-Cl4- and a cluster cation {Mo3(μ3-S) (S2)3 (dtp)3]2Cl} + which is a double-trinuclear molybdenum cluster formed by sharing a chlorine atom with six weak Cl -S bonds of about 2.936-3. 145A.
