| Abstract: | Dicerium(IV) tetrachromate(VI) dihydrate, Ce(CrO4)4·2H2O, has been prepared from an acidic aqueous solution at room temperature. Its novel crystal structure, which was solved from single‐crystal X‐ray diffraction data, is built from isolated CrO4 tetrahedra and isolated Ce(O,H2O)n (n = 8 and 9) polyhedra. All atoms are in general positions. The mean Ce—O and Cr—O bond lengths are 2.358 and 1.651 Å, respectively. Comparisons are drawn with the structure of CeIV(CrO4)2·2H2O. |
