Abstract
The structure and preparation of a new luminescent microporous terbium silicate Na3TbSi3O9.3H2O (TbSiO-CJ1) crystallized in the enantiomorphic space group P212 121 were analyzed. The structure was featured by a A-Co(en)3 such as chiral unit of [TbSi6O9] and contained helical sechser silicate chains and 9- ring channels. TbSiO-CJI was prepared by the mild hydrothermal reaction of a mixture of fumed silica and water in a 1.0:0.12:8.46:58 molar ratio at 230°C for 6 days in a Teflon lined stainless steel autoclave. The single crystal unit revealed that TbSiO-CJI is composed of a macroanionic [TbSi3O9]3- framework. The Na positive ions residing in the channels compensated the negative charge of the inorganic framework. Results show that a new terbium silicate has been synthesized under mild hydrothermal conditions.
