Abstract

New ring silicates Cs4Tm2[Si4O12](OH)2 and Cs4(Tm,Tb)2[Si4O12](OH)2 have been synthesized by the hydrothermal method. A structural analogy is revealed between them and the previously studied silicates K4Sc2(OH)2(Si4O12) and K2Sc[Si2O6]F. Their crystal structures are identified as orthorhombic merohedral twins by the lost element of tetragonal symmetry. The structures of new ring silicates are related to those of fresnoite and tetragonal melilite.

环状硅酸盐 Cs4Tm2[Si4O12](OH)2 和 Cs4(Tm,Tb)2[Si4O12](OH)2 作为孪晶孪晶

摘要

采用水热法合成了新型环状硅酸盐Cs 4 Tm 2 [Si 4 O 12 ](OH) 2和Cs 4 (Tm,Tb) 2 [Si 4 O 12 ](OH) 2 。它们与先前研究的硅酸盐 K 4 Sc 2 (OH) 2 (Si 4 O 12 ) 和 K 2 Sc[Si 2 O 6之间存在结构相似性]F。由于四方对称性的缺失,它们的晶体结构被鉴定为斜方晶系孪晶。新的环状硅酸盐的结构与磷镁长石和四方黄长石的结构有关。
