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H_(34)Ni_(5)Mo_(12)O_(52)(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/cm^(3),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Ni^(2+),由12个MoO_(6)八面体和4个NiO_(6)八面体通过共角和共边构成。
The title compound with formula H_(34)Ni_(5)Mo_(12)O_(52)(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/cm^(3),=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[NiMo^(Ⅴ)_(12)O_(40){Ni(H_(2)O)_(3)}_(4)]^(10-)of the title compound,Ni^(2+)occupies the centre and twelve MoO_(6)octahedra and four NiO_(6)octahedra form the cluster anion by sharing corner and edge.
