Synthesis, characterization, and crystal structure of hexakis(1-methyl-1H-imidazole-κN ³)zinc(II) dinitrate

The synthesis of the title compound, [Zn(C 4 H 6 N 2 ) 6 ](NO 3 ) 2 , is described. This complex consists of a central zinc metal ion surrounded by six 1-methylimidazole ligands, charge balanced by two nitrate anions. The complex crystallizes in the space group P 3̄. In the crystal, the nitrate ions are situated within the cavities created by the [Zn( N -Melm) 6 ] 2+ cations, serving as counter-ions. The three oxygen atoms of the nitrate ion engage in weak C—H...O interactions. In addition to single-crystal X-ray diffraction analysis, the complex was characterized using elemental analysis, 1 H NMR, 13 C NMR, and FTIR spectroscopy.
