摘要
采用低温技术,用 X 射线单晶衍射法测定了标题化合物的结构.晶体属 P4/mnc 空间群,a=12.515(3),c=17.636(7),Z=2.用788个独立可观测反射精修所有结构参数得 R=0.061.钼钒磷杂多酸阴离子中,PO_4四面体是无序的,P—O 键长1.54.M(Mo,V)是6配位,M—O 键长1.62—2.48.K 是7配位,K—O 键长2.84—3.10.
The crystal structure of the title compound was determined from single crystalX-ray diffraction at -90℃.The complex orystallizes in the tetragonal P4/mnc,Z=2,α=12.515(3),c=17.636(7)(?).The structure was solved by Patterson and Fouriertechniques and refined by least-squares to R=0.061 for 788 reflections.The centralPO_4 is disordered,P—O=1.54(?),M(M=Mo or V) is 6-coordinate,M—0=1.62—2.48(?),K is 7-coordinate,K—O=2.84—3.10(?).
