The γ polymorph of cerium(III) sulfide adopts a cation-deficient form of the Th 3 P 4 structure. 8 out the 9 metal positions in the Th 3 P 4 structure are occupied by cerium in γ-Ce 2 S 3, with the remainder as vacancies. This composition can be represented by the formula Ce 2.667 0.333 S 4.
Cerium sulfide forms yellow crystalline solid of cubic syngony crystals, space group Fm3m, cell parameter a = 0.5780 nm, Z = 4, of NaCl-type structure. [citation needed] The compound melts congruently at a temperature of 2450 °C.
Cerium nitrates also form 4:3 and 1:1 complexes with 18-crown-6 (the ratio referring to that between cerium and the crown ether). Classically CAN is a primary standard for quantitative analysis. [8] [9] Cerium(IV) salts, especially cerium(IV) sulfate, are often used as standard reagents for volumetric analysis in cerimetric titrations. [10]

Cerium(IV) sulfate, also called ceric sulfate, is an inorganic compound. It exists as the anhydrous salt Ce(SO 4) 2 as well as a few hydrated forms: Ce(SO 4) 2 (H 2 O) x, with x equal to 4, 8, or 12. These salts are yellow to yellow/orange solids that are moderately soluble in water and dilute acids.
Since 2019, a mole of any substance has been redefined in the SI as the amount of that substance containing an exactly defined number of particles, 6.022 140 76 × 10 23. The molar mass of a compound in g/mol thus is equal to the mass of this number of molecules of the compound in grams.
