Tris(ethylenediamine)zinc(II) hexafluoridosilicate

Abstract

The title compound, [Zn(C2H8N2)(3)](SiF6), was synthesized ionothermally using choline chloride-imidazolidone as solvent and template provider. In the crystal structure, the anions and cations are located on special positions of site symmetry 3.2 and show a typical octahedral geometry. The Zn-II ion is coordinated by six N atoms from three ethylenediamine molecules. The crystal structure displays weak hydrogen bonding between [SiF6](2-) anions and the ethylenediamine NH hydrogen atoms.
