LiFe3+(Se2O5)2and its structure relationships toMe2+(Se2O5) compounds

摘要

LiFe3+(Se2O5)2was obtained by hydrothermal synthesis and the structure was investigated by single crystal X-ray diffraction methods:a=5.987(2)Å,b=6.760(2)Å,c=10.295(3)Å,V=416.66Å3;Z=2, space group Pnc2,R=0.028,Rw=0.028 for 2002 independent reflections (sinϑ/λ≤0.90Å−1). The crystal structure of LiFe3+(Se2O5)2is closely related with that ofMe2+(Se2O5) compounds (Me=M
