The effect of substitution on the phosphorus atom of dithiophosphinates was examined by synthesising complexes of Etdtpi, Cl2dtpi and MeCldtpi with Cr(III), Mn(II), Fe(III), Co(II) and Ni(II).The esr spectra of Fe(III) derivatives were indicative of distortion from octahedral symmetry while for those of Cr(III) derivatives a large reduction of the spin-orbit coupling constant (λ) was observed, indicating the high nephelauxetic effect of these sulphur ligands.Wherever possible the ligand field parameters (10 Dq, B and β) were evaluated and from the 10 Dq values the position of these sulphur ligands were found to be lower in the spectrochemical series compared to many other dithioligands.
