Acta Crystallographica, 1962•Wiley Online LibraryWith 252 Fo (hkl), least-squares solutions for the structure of Sc2Si20 have been found in
each of the space groups Cm, C2 and C2/m. After discussion, the correct space group is
concluded to be C2/m and the Si-O-Si angle is therefore 180 [/n agreement with
Zachariasen (1930)]. The Si-O distances are all close to 1.62/~; the Sc-O distances average
2.13/~.
