title: Stoichiometric CeCuOS--a well-behaved Ce(III) layered oxysulfide.
abstract: The reported anomalously small cell volume and magnetic moment of the layered oxysulfide CeCuOS are apparently the results of copper deficiency arising from exposure to ambient moist air; the stoichiometric compound does exist and is a well-behaved Ce(III) compound.
