The title compounds, tetraphenylphosphonium chlorobis(diethyldithiocarbamato-S,S)cadmium(II), (C₂₄H₂₀P)-[CdCl(C₅H₁₀NS ₂)₂], (1), and tetraphenylphosphonium bromobis(diethyldithiocarbamato-S,S)cadmium(II), (C₂₄-H₂₀P)[CdBr(C₅H₁₀NS ₂)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) A in (2); Cd-Cl and Cd-Br 2.462 (1) and 2.626 (1) A, respectively.
