## Description

- description: 'Single crystal particles of Na2BaZr[SiO4]2 [systematic name: disodium
    barium zirconium bis­(orthosilicate)] and Na2BaHf[SiO4]2 [disodium barium hafnium
    bis­(orthosilicate)] were extracted from grain-grown polycrystals obtained by
    heating compacts of binary oxide mixtures at 1473 K. Single crystal X-ray diffraction
    analysis revealed that these are isostructural orthosilicates with a glaserite-type
    crystal structure, in which all sites of X, Y, M, and T in the general formula
    XY2[M(TO4)2] are fully occupied by atoms of different elements. The crystal structures
    of the title compounds were refined in space group P3 under consideration of a
    two-component twin model. The SiO4 tetra­hedra are rotated approximately ±10.2°
    from the mirror plane of space group P3m around an axis parallel to [001].'
