A new polymorph of lutetium polyphosphate, Lu(PO(3))(3), was found to be isotypic with the trigonal form of Yb(PO(3))(3). Two of the three Lu atoms occupy special positions (Wyckoff positions 3a and 3b, site symmetry ). The atomic arrangement consists of infinite helical polyphosphate chains running along the c axis, with a repeat period of 12 PO(4) tetra-hedra, joined with LuO(6) octa-hedra.
发现一种新的多聚磷酸镥多晶型物Lu(PO(3))(3),它与Yb(PO(3))(3)的三方晶型同型。三个Lu原子中的两个占据特殊位置(Wyckoff位置3a和3b,点群对称性)。原子排列由沿c轴延伸的无限螺旋状多磷酸盐链组成,重复周期为12个PO(4)四面体,并与LuO(6)八面体相连。
