A Ni(II) dithiocarbamates with the tridentate P,P,P-ligand of composition [Ni(pe2dtc)(triphosI)]X (triphosI = C34H33P3 = bis(2-diphenylphosphinoethyl) phenylphosphine, pe2dtc = dipentyldithiocarbamate, X = Cl, PF6, ClO4), [Ni(bz2dtc)(triphosI)]X (bz2dtc = dibenzyldithiocarbamate, X = Cl, PF6) and [Ni(cetdtc)(triphosI)]X (cetdtc = cyclohexylethyldithiocarbamate, X = Cl, PF6, BPh4, ClO4) have been synthesized and studied by thermal analysis, IR and UV/VIS spectroscopy, 31P{1H}-NMR spectroscopy, magnetochemical and conductivity measurements. All complexes are diamagnetic, 1:1 electrolytes. X-ray structural analysis was solved for the [Ni(pe2dtc)(triphosI)]PF6 and [Ni(bz2dtc)(triphosI)]PF6; the presence of NiS2P3
