title: New isostructural transition metal complexes with a non-innocent dithiolate ligand.
abstract: Three new complexes with 3,6-dichlorobenzene-1,2-dithiol (bdtCl2), namely methyltriphenylphosphonium bis(3,6-dichlorobenzene-1,2-dithiolato-κ(2)S,S')cobaltate(1-), (C19H18P)[Co(C6H2Cl2S2)2], (I), bis(methyltriphenylphosphonium) bis(3,6-dichlorobenzene-1,2-dithiolato-κ(2)S,S')cuprate(2-) dimethyl sulfoxide disolvate, (C19H18P)2[Cu(C6H2Cl2S2)2]·2C2H6OS, (II), and methyltriphenylphosphonium bis(3,6-dichlorobenzene-1,2-dithiolato-κ(2)S,S')cuprate(1-), (C19H18P)[Cu(C6H2Cl2S2)2], (III), have been synthesized and characterized by single-crystal X-ray diffraction. The X-ray structure analyses of all three complexes confirm that the four donor S atoms form a slightly distorted square-planar coordination arrangement around the central metal atom. An interesting finding for both the Cu(II) and Cu(III) complexes, i.e. (II) and (III), respectively, is that the coordination polyhedra are principally the same and differ only slightly with respect to the interatomic distances.
