Xh. Bu et al., K2BE2SI3O9, A POTASSIUM BERYLLIUM SILICATE FRAMEWORK BUILT FROM EDGE-SHARING BE-O TETRAHEDRA AND 3-RING SILICATE TETRAHEDRA, Acta crystallographica. Section C, Crystal structure communications, 52, 1996, pp. 2662-2664
Dipotassium diberyllium trisilicon nonaoxide, K2Be2-Si3O9, was synthes
ized at high temperature and high pressure and has a three-dimensional
framework structure containing six-ring channels along the b axis. Th
e framework is built from cyclic trimers of silicate tetrahedra and ed
ge-sharing Be-O tetrahedra.
