The Five-Coordinate Cadmium Halide Bis(diethyldithiocarbamate) Complexes [PPh4][Cd(S2CNEt2)2Cl] and [PPh4][Cd(S2CNEt2)2Br]
摘要:
The title compounds, tetraphenylphosphonium chloro-bis(diethyldithiocarbamato-S,S)cadmium(II), (C24H20P) [CdCl(C5H10NS2)(2)], (1), and tetraphenylphosphonium bromobis(diethyldithiocarbamato-S,S)cadmium(II), (C-24 H20P)[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) Angstrom in (2); Cd-Cl and Cd-Br 2.462 (1) and 2.626 (1) Angstrom, respectively.
