The crystal structures of two new quaternary compounds, viz. dicerium orthosilicate selenide and dicerium orthosilicate telluride, Ce(2)(SiO(4))Q (Q = Se or Te), have been determined from single-crystal X-ray diffraction data. Each structure comprises infinite chains of SiO(4) tetrahedra separated by Ce and Q atoms. The site symmetries are Ce m and 2, Si 2 and Q m. The O atoms are in general positions.
两种新型四元化合物，即原硅酸铈硒化物和原硅酸铈碲化物，Ce₂(SiO₄)Q（Q = Se或Te）的晶体结构已通过单晶X射线衍射数据确定。每种结构都包含由Ce和Q原子隔开的无限长的SiO₄四面体链。位点对称性为Ce m和2，Si 2和Q m。O原子处于一般位置。
