Crystal structure of a lithium zinc borophosphate

A borophosphate compound Li[ZnBP2O8(H2O) 2]·H2O,was prepared by hydrothermal synthesis.X-ray single crystal diffraction analysis shows that the crystal structure of Li[ZnBP2O8(H2O) 2]·H2O is hexagonal,space group is P6522 with Z=6.Mr = 1 956.72,a=0.944 67(8) nm,c=1.563 97(13)nm,V=1.208 70(18)nm3,Dc=2.688 g/cm3,F(000)=966,R=0.033 2,Wr=0.073 0,and 768 reflections is observed within I2σ(I).The crystal structure of the compound contains infinite one-dimensional borophosphate ribbons 1∞3-,which is built by BO4 and PO4 tetrahedra arranged around 65 screw axes.
