✦ Synopsis

Abstraet--Polycrystalline samples of Cu(Me2dtp)(Me2dtc) and Ni(Me2dtp)(Me2dtc) complexes are studied by means of EPR, ENDOR, and vibrational normal coordinate analysis. On the basis of EPR and ENDOR experimental results, the spin density distribution on JH and 3~p nuclei of the mixed iigand and parent copper dithiophosphate and dithiocarbamate complexes is compared. Comparison between vibrational spectra and normal coordinate analysis data on Ni(Me2dtp)(Me2dtc), Ni(Me2dtP)2 and Ni(Me2dtc)2 enabled the conclusion that the structure of the NiS4 fragment in the mixed complex is retained close to that in the bis-chelate complexes.
