Zinner in 1979.[2][3] The crystals have a monoclinic polymeric structure were each methanesulfonate ion forms bonds with two cerium atoms, which present a coordination number of 8.[4] The anhydrous salt is formed by water loss at 120 °C. Similar methanesulfonates can be prepared with other lanthanides.[5] Cerium(III) methanesulfonate in solution is used as a precursor of electrogenerated cerium(IV), which is a strong oxidant and whose salts can be used in organic synthesis.[6] The same principle of Ce(IV) electrogeneration is the fundamental reaction in the positive half-cell of the zinc–cerium battery.
