Sumario:The title compound, dicerium(III) oxidodisilicate, Ce(2)[Si(2)O(7)], was obtained as a by-product in its H-type structure after attempts to synthesize CeSb(2)O(4)Cl from fused silica ampoules. It crystallizes isotypically with H-La(2)[Si(2)O(7)]. The four crystallographically distinct Ce(III) cations form distorted square anti­prisms, capped square anti­prisms, and bicapped square anti­prisms as coordination polyhedra consisting of oxygen atoms. Four crystallographically different silicon atoms recruit the centers of two different isolated [Si(2)O(7)](6–) units. [Image: see text]
