摘　　要：［Ｍｏ３（μ３－Ｏ）（μ－Ｓ）３（μ－ＯＡｃ（ｄｔｐ）３（ｐｙ）］和［Ｍｏ３（μ－Ｓ）３（μ－ＯＡｃ（ｄｔｐ）３－（ｐｙ）］（ｄｔｐ＝Ｓ２Ｐ（ＯＣ２Ｈ５）２＾－）族合物分别与金属化合物ＢｉＩ３和ＳｂＢｒ３进行原子簇反应均能获得意外产物｛［Ｍｏ３（μ３－Ｓ）（μ－Ｓ２）２（ｄｔｐ）３］（μ３－Ｓ）（η＾３－Ｓ２）［Ｍｏ２（μ３－Ｓ）（μ－Ｓ）３（μ－ＯＡｃ）（ｄｔｐ）２］｝六核钼簇。From the reaction of [Mo_3 (μ_3-O)(μ-S)_3 (dtp)_3(μ-OAc)(py)] with BiI_3 or of [Mo_3 (μ_3-S)-(μ-S)_3 (μ-OAc) (dtp)_3(py)] with SbBr_3 (dtp = S_2P(OC_2H_5)_2￣-) ,the novel hexanuclear molybdenum cluster { [Mo_3 (μ_3-S)(μ-S_2)_2(dtp)_3](μ_3-S)(η￣3-S_2)[Mo_3(μ_3-S)(μ-S)_3(μ-OAc)(dtp)_2]} was unexpectedly obtained. The structure can be viewed as a raft-like {Mo_6 } cluster linked by two {Mo_3} cluster units through one(μ_3-S) and one"handle coordination fashion"η￣3-(S_2) group. The presence of S-S supramolecular interaction between the adjacent {Mo_6} clusters results in the formation of the {Mo_6}---{Mo_6} chain along α axis in the unit cell stacking. Crystal data:triclinic, space group P1, a= 13. 726(4) . b=14. 899(4) ,c= 17. 610(5),α=107. 43(2) ,β= 81. 63(3) ,γ=103. 36(2)°,V=3332(4), Z=2. R=0. 056(R_ω=0. 061) for 5771 independent absorption corrected data.
