Bis(N,N,N-trimethylethanaminium) bis(1,4-tetraselenido-²Se¹,Se⁴)cadmate

J. Kim and K.-W. Kim

Abstract: 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.
