A series of NiII complexes with the O,O′-di-isoamylester of dithiophosphoric acid and nitrogen-donor ligands of composition [Ni(i-Am2dtp)2(L)]; [dtp = O2PS2; L = 2,2′-bipyridine (bpy); 1,10-phenanthroline (phen); 5-nitro-1,10-phenanthroline (nphen); 4,7-diphenyl-1,10-phenanthroline (baphen); 2,9-dimethyl-1,10-phenanthroline (neo), 2-aminomethylpyridine (amp), 2-(2-aminoethyl)pyridine (aep), 2,2′-dipiridylamine (dpa), 1,2-diaminopropane (1,2-dap) or trans 1,2-diaminocyclohexane (dch)] have been prepared. The compounds have been characterized by elemental analyses (C,H,N,S), electronic and i.r. spectroscopy, magnetic and conductivity measurements and by cyclic voltammetry. The results show that all complexes behave as non-electrolytes in acetone. Electronic spectra and magnetic moments suggest a distorted cis-octahedral geometry around the NiII atom [μeffB ∈ <3.10, 3.40 >], except for [Ni(i-Am2dtp)2(aep)], where the measured temperature dependence of the magnetic susceptibility proved the tetrahedrally coordinated nickel [4.06 μeffB (298 K) – 3.20 μeffB (80 K)]. In the [Ni(i-Am2dtp)2(neo)] complex, the nickel atom is penta-coordinated. The X-ray crystal and molecular structure of [Ni(i-Am2dtp)2(1,2-dap)] has been determined.
