Description

NaPr(SeO4)2 structure is decoded (autodiffractometer CAD-4). Triclinic cell parameters are as follows: a=6.639(2), b=7.118(1), c=7.36(1) A, α=99.16(2) deg, β=96.93(2) deg, γ=89.77 (3) deg, p.gr. P1-bar, Z=2. Structure is of carcass type, built on CaSO4 anhydride structure base with 2Ca→TR3++Na+-type ordered substitution. Structural comparative crystallochemical analysis of anhydride and NaPr(SeO4)2 and NaNd(SO4)2 isostructural double salts is carried out
