摘要
在水热的条件下合成了1个标题的Mo-Ni-O异核簇合物,化学式为H34Ni5Mo12O52 (Mr = 2311.10),用单晶X射线衍射方法测定了它的结构,该晶体属四方晶系,I41/amd空间群,晶胞参数为a = 15.319(2),c = 30.645(3) ,V = 7191.2(16) 3,Z = 4,Dc = 2.135 g/cm3,μ= 3.369 mm-1, F(000) = 4376, 1036个可观察衍射点(I > 2s(I)),最终结构偏离因子R = 0.0560,wR = 0.1632,S = 1.002。该化合物簇阴离子笼中心是Ni2+,由12个MoO6八面体和4个NiO6八面体通过共角和共边构成。
The title compound with formula H34Ni5Mo12O52 (Mr = 2311.10) was synthesized under hydrothermal conditions and its crystal structure was determined by X-ray diffraction. It belongs to tetragonal system, space group I41/amd with a = 15.319(2), c = 30.645(3) ? V = 7191.2(16) ?, Z = 4, Dc = 2.135 g/cm3, = 3.369 mm-1, F(000) = 4376 and S = 1.002. The final R = 0.0560 and wR = 0.1632 for 1036 observed reflec- tions (I > 2s(I)). The result of the structure analysis indicates that in the anion [NiMoⅤ12O40{Ni(H2O)3}4]10- of the title compound, Ni2+ occupies the centre and twelve MoO6 octahedra and four NiO6 octahedra form the cluster anion by sharing corner and edge.
