摘　　要：The cubane-type mixed Mo W cluster[Mo2W2S4 (OAc)2(dtp)3 (dtpH)]·CH2Cl2 (dtp= (EtO)2PS2, dtpH = (EtO)2PS (SH) has been prepared by reduction and addition reaction between dinuclear W2S4 (dtp)2 and Mo(CO)6 in HOAc and Ac2O solution in the presence of dtp-ligand. Crystallographic data: Mr=1632. 71,monoclinic, space group P2/n, a=13. 146 (8), b=11. 961 (5),c=17. 157 (9) β =105. 99(8)°, V=2593(8), Z=2, Dc=2. 09 /cm￣3 ,λ(MoKa) =0.71073 ,F (000)=1578, final R=0. 029, Rw = 0. 041 for 3765 unique intensity data [I≥4σ (I)]. The result of X-ray study and elemental analysis indicated that, in the crystal lattice, molybdenum and tungsten are statistically distributed in the metal positions each with 0. 5 fractional occupation.
