由[Mo~3(μ~3-O)(μ-S)~3(dtp)~4(H~2O)和PbI~3^-在咪唑存在下反应获得异四核混合簇[Mo~3(PbI~3)S~4(dtp)~3(C~3H~4N~2)~3][(CH~3)~2CO]~2(2)[dtp=S~2P(OC~2H~5)~2^-]。簇合物属斜方晶系,空间群P~b~c~a(No.61),晶胞参数为a=2.3590(3),b=1.9161(5),c=2.6458(9)nm,V=11.959(6)nm^3,Z=8。结构最终偏离因子R=0.067。此四核簇分子具有[Mo~3PbS~4]类立方烷簇芯,簇分子整体对称性接近C~3~v。在同一不对称单元中,簇分子的咪唑环以(NH)和溶剂丙酮分子的氧原子形成O---H---N氢键。

A new heterotetranuclear cluster compound [Mo~3(PbI~3)S~4(dtp)~3 (C~3H~4N~2)~3][(CH~3)~2CO]~2 (2) was prepared by the reaction of [Mo~3OS~3(dtp)~4(H~2O)] with PbI~3^- in the presence of imidazole (C~3H~4N~2). The cluster structure consists of the neutral Mo-Pb tetranuclear cluster with a cubane-like [Mo~3PbS~4] core and the solvent acetone (CH~3)~2CO. There are hydrogen bonds O- - -H---N between the oxygen atom of the acetone and the (NH) of the imidazol ring of the Mo-Pb Cluster. Crystallographic data: Orthorhombic P~b~c~a (No.61). a=2.3590(3), b=1.9161(5), c=2.6458(9)nm, V=11.959(6) nm^3, Z=8. Final R=0.067.
