| Abstract: | The crystal structure of RbSb2F7 was determined by single crystal X-ray diffraction methods. The antimony atom coordination is of the AX6E type, either monocapped octahedral or the distorded 2.2.2.1 arrangement. The anion (Sb2F7)x-x forms a polymeric layer parallel to the bc plane. There is an Sb-F-Sb bridge intermediate between the symmetric and asymmetric bridges of CsSb2F7 and KSb2F7 respectively. |
