EPR INVESTIGATIONS ON THE NI(III), PD(III), PT(III) AND CU(II) BIS-CHELATES OF THE DITHIOLENE PARENT LIGAND BIS(CIS)ETHYLENEDITHIOLATE S2C2H2(2-)

摘要

EPR spectroscopic investigations on the Ni-III, Pd-III, Pt-III and Cu-II complexes of the dithiolene parent ligand S2C2H22- are reported and compared to those of the classic dithiolene ligands S2C2(C6H5)(2)(2-) and S2C2(CN)(2)(2-).The ligand periphery was found to has only a small influence on the distribution of the spin-density which is mainly localized in the MS4C4 coordination sphere.
