The title compound, (EtMe3N)2[Cd(Se4)2], which has been prepared by reaction of CdI2, K2Se4 and EtMe3NI in dimethylformamide, is the first example of a [Cd(Se4)2]2- anion stabilized by alkylammonium counter-ions. The Cd atom in the complex [Cd(Se4)2]2- anion is tetrahedrally coordinated by two chelating tetraselenide ligands, and both CdSe4 rings exhibit an envelope conformation.
