英文摘要: Abstract(#br)A new cubic borate, Yb 3 [BO 3 ](OH) 6 ⋅2.1H 2 O was synthesized in a multi-component hydrothermal system Yb 2 (CO 3 ) 3 : B 2 O 3 : P 2 O 5 = 5 : 2: 1 (T = 280 °C; P = 90–100 atm; pH = 3). The crystal structure was studied using single crystal X-ray analysis. The structure has been refined in the space group I 432, possesses the unit cell parameter a = 12.2808(15) Å. A microporous positively charged framework is formed by predominant Yb cations coordinated by O 2− , OH − as a tetragonal antiprism, which are linked together via common edges and vertices. The extra framework BO 3 triangles center narrow channels, directed along 3-fold axis, are perpendicular to them and clamped between large Yb polyhedra. The large cavities with the effective cavity width 7.7 Å are filled by...
