The Five-Coordinate Cadmium Halide Bis(diethyldithiocarbamate) Complexes [PPh₄][Cd(S₂CNEt₂)₂Cl] and [PPh₄][Cd(S₂CNEt₂)₂Br]

The title compounds, tetraphenylphosphonium chloro bis(diethyldithiocarbamato-S,S)cadmium(II), (C₂₄H₂₀P)[CdCl(C₅H₁₀NS₂)₂], (1), and tetraphenylphosphonium bromobis(diethyldithiocarbamato-S,S)cadmium(II), (C₂₄H₂₀P)[CdBr(C₅H₁₀NS₂)₂], (2), are isomorphous. The compexes are mononuclear with coordination spheres of the types S₄Cl and S₄Br, respectively. The central Cd atom is linked to four S atoms and two bidentate dithiocarbamate ligands and to the halide atom. The resulting Cd atom coordination geometry is halfway between trigonal bipyrimidal and square pyramidal. Principal dimensions include Cd-S 2.573 (1)-2.682 (1) in (1) and 2.571 (3)-2.736 (2) Å in (2). The Cd-Cl and Cd-Br distances are 2.462 (1) and 2.626 (1) Å, respectively.
