Three new NS2 aza-dithia S-aryl ligands have been synthesized and their Cu(II) and Cu(I) complexes reported. The ligand donor properties of these ligands are compared with similar NS2 S-alkyl molecules. The NS2 S-aryl ligands are softer and display a larger ir-acid character than the corresponding NS2 S-alkyl compounds. The molecular structure of [2,6-Bis(((2-methoxy- carbonyl)phenyl)thio)methyl)pyridine]dichlorocopper(II) has been solved by X-ray diffraction methods: C23H21Cl2CuNO4S2, monoclinic, space group P21/c, a = 20.138 (4) Å, b = 8.173 (1) Å, c = 15.533 (3) Å, β = 111.20 (2)°, V= 2384 (1) Å3, Z = 4, Dc = 1.600 g·cm−3. © 1991, American Chemical Society.
