The crystal structures of two new quaternary compounds, viz. dicerium orthosilicate selenide and dicerium orthosilicate telluride, Ce 2(SiO4)Q (Q = Se or Te), have been determined from single-crystal X-ray diffraction data. Each structure comprises infinite chains of SiO4 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.
