- Аннотация: Two aluminophosphate analogues of the mineral pollucite with the general formula Cs2(M,Al)3P3O12 (where M=Cu or Mn) have been synthesized by high temperature flux and structurally characterized using the single crystal X-ray diffraction. Both samples crystallize in cubic I4132 space group, Z=8, with a = 13.5911(5) and a = 13.8544(7) for Cu and Mn-loaded phases, respectively. Theirs framework structures are based on the ANA-type topology and exhibit the partial ordering of the metal (M/Al) and phosphorus (P) cations over the tetrahedral sites. The regular changes in cell dimensions and volumes in the row Cs2(Cu,Al)3P3O12→Cs2(Mn,Al)3P3O12 obviously correspond to increasing radii of the transition metal. The crystal chemical analysis of both pollucite-like phases shows correlations between the difference in the radii size of tetrahedral cations and the degree of distortion of flexible ANA-type framework due to decreasing of the intertetrahedral angles (T-O-T). Magnetic susceptibility measurements indicate that both compounds are paramagnets in the temperature range of 2–300 K.
