Structure and properties of tecto-gallosilicates II. Sodium chloride, bromide and iodide sodalites

The crystal structures of the gallosilicate so dalites Na₈[GaSiO₄]₆Cl₂, Na₈[GaSiO₄]₆Br₂ and Na₈[GaSiO₄]₆I₂ were refined from X-ray powder data in the space group P-43n: a = 894.70 pm, V = 0.7162 nm³, R_WP = 0.066, R_P = 0.050, R_I = 0.011, a = 900.83 pm, V = 0.73102 nm³, R_WP = 0.066, R_P = 0.051, R_I = 0.016 and a = 908.36 pm, V = 0.74951 nm³, R_WP = 0.050, R_P = 0.036, R_I = 0.013 for 4000 data points and 14 variable positional parameters in each case for the chloride, bromide and iodide compound, respectively...
