从Na_2 O-Sc_2 O_3-B_2 O_3熔体中自发晶化获得了三钪双钪(正硼酸盐)单晶Na_3Sc(BO_3)_2。晶体结构具有由平面[BO 3]3−基团和扭曲的ScO 6八面体组成的三维框架,其中Na原子位于空腔中。Sc原子占据特殊位置(维科夫位置2b,位置对称性-1),并且在两个Na原子中,一个占据特殊位置(维科夫位置2c,位置对称性-1)。
Single crystals of tris­odium scandium bis­(orthoborate), Na3Sc(BO3)2, have been obtained by spontaneous crystallization from an Na2O–Sc2O3–B2O3 melt. The crystal structure features a three-dimensional framework composed of planar [BO3]3− groups and distorted ScO6 octa­hedra with Na atoms in the cavities. The Sc atom occupies a special position (Wyckoff position 2b, site symmetry -1) and of the two Na atoms, one occupies a special position (Wyckoff position 2c, site symmetry -1).
