摘要
在水热的条件下合成了1个多聚钒硼酸盐[Ni(en)2]6H2[(VO)12O6B18O42]15H2O,化学式为C24H128B18N24Ni6O75V12(Mr=3111.62),用单晶X射线衍射方法测定了它的结构,该晶体属三方晶系,R-3空间群,晶胞参数为a=13.942(2)?=96.476(2),V=2653.9(5)?,Z=1,Dc=1.947g/cm3,=21.55cm-1,F(000)=1574,2108个可观察衍射点(I>2(I)),最终结构精修到偏离因子R=0.0594,wR=0.1398,S=1.009。在该化合物的结构中,18员环的B18O42通过18个B(3-O)V键被2个V6O15簇夹在中间,6个[Ni(en)2]基团分别通过2个Ni(3-O)B与B18O42环相连。
The title compound with formula C24H128B18N24Ni6O75V12 (Mr = 3111.62) has been synthesized under hydrothermal conditions and its crystal structure was determined by X-ray diffraction. It belongs to trigonal system, space group R-3with a = 13.942(2) ? ?= 96.476(2), V = 2653.9(5) ?, Z = 1, Dc = 1.947 g/cm3, ?= 21.55 cm-1, F(000) = 1574 and S = 1.009. The final R and wR are 0.0594 and 0.1398 for 2108 observed reflections with I > 2s(I), respectively. In the structure of this compound there exists an 18-membered ring of B18O42 sandwiched between two vanadium-oxygen clusters V6O15 by eighteen B(3-O)V bonds, and six [Ni(en)2] were connected with the B18O42 ring by two Ni(3-O)B, respectively.
