【摘要】由[Mo₃（μ₃-O）（μ-S）₃（dtp）₄（H₂O）]和PbI₃^-在咪唑存在下反应获得异四核混合簇[Mo₃-（PbI₃）S₄（dtp）₃（C₃H₄N₂）₃][（CH₃）CO]₂（2）[dtp=S₂P（OC₂H₅）₂^-].簇合物属斜方晶系,空间群P_bca（No.61）,晶胞参数为α=2.3590（3）,b=1.9161（5）,c=2.6458（9）nm,V=11.959（6）nm³,Z=8.结构最终偏离因子R=0.067.此四核簇分子具有[Mo₃PbS₄]类立方烷簇芯,簇分子整体对称性接近C_3v.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.更多还原

【Abstract】 A new heterotetranuclear cluster compound [Mo3(PbI3)S4(dtp)3(C3H4N2)3]-[(CH3)2CO]2(2) was prepared by the reaction of [Mo3OS3(dtp)4(H2O)] with PbI3- in the presence of imidazole (C3H4N2). The cluster structure consists of the neutral Mo-Pb tetranuclear cluster with a cubane - like [ Mo3PbS4 ] core and the solvent acetone (CH3)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 Pbca ( No. 61) . a = 2.3590(3),b= 1.9161(5),c = 2.6458(9)nm,V = 11.959(6)nm3,Z = 8.Final R =0.067.更多还原
