Four new salts with low melting points of the general formula (EMIm)[NiBr3(L)] (EMIm = 1-ethyl-3-methyl-imidazolium) with L = N-methylimidazole (NMIm), N-methylbenzimidazole (NMBIm), quinoline (quin), and triphenylphosphane (PPh3) were prepared and characterized by means of elemental analysis, IR, NMR, and UV-vis spectroscopy. Magnetic properties were deduced from NMR data using the EVANS method. All four compounds are paramagnetic with magnetic moments close to the spin-only values of the tetrahedrally coordinated Ni(II) ion. Molecular and crystal structures were obtained by single crystal X-ray diffraction investigations. Melting points are determined to have values between 110 °C, (EMIm)[NiBr3(NMIm)] and 168 °C, (EMIm)[NiBr3(PPh3)]. They exceed the maximum temperature required to call them "Ionic Liquids". Decomposition has been found to occur above 200 °C and to depend largely on the type of organic ligand coordinated to Ni(II).
