Abstract

The ionothermal synthesis and spectroscopic, thermal and structural characterization of two new compounds [Cu(C4H6N2)4]Br2 (1) and [Ni(C4H6N2)4]Br2 (2) [(C4H6N2)= N-methylimidazole] are reported. In both 1 and 2, the central metal Cu (or Ni) ion adopts a square planar geometry and is bonded to the N-atoms of four terminal N-methylimidazole ligands.

Two new complexes, Cu(C4H6N2)4Br2 and Ni(C4H6N2)4Br2 composed of complex cation formed by Cu2+ or Ni2+ coordinated by four N-methylimidazole ligands and bromide anions were ionothermally synthesized in an ionic liquid medium and characterized by X-ray single crystal diffraction, FT-IR, TGA and elemental analysis.
