Mononuclear Bis(3-aminoquinoline)Zn(II) complexes: Synthesis and structural characterization

A series of two new Zn(II) complexes derived from 3-aminoquinoline are reported. The complexes were synthesized by the interaction of 3-aminoquinoline and Zn(II) ions in 2:1 molar ratio. The structure of synthesized complexes is investigated by elemental analyses, ESI-MS, FT-IR, 1H and 13C NMR and UV–Vis spectroscopic studies. A single crystal X-ray diffraction measurement study reveals tetrahedral geometry around the zinc ion, and existence as a neutral discrete molecule.
