Moore P B , Shen J , American Mineralogist , 68 (1983) p.996-1003, Cerite, RE9(Fe3+,Mg)(SiO4)6(SiO3OH)(OH)3: Its crystal structure and, relation to whitlockite, Note: Thermal parameters have been changed to match symmetry constraints,, It is likely that the structure was refined wrong to begin with.
