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 ZnII 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.
