Tris(ethyl-enediamine)zinc(II) hexa-fluorido-silicate.

ABSTRACT: The title compound, [Zn(C(2)H(8)N(2))(3)](SiF(6)), 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 octa-hedral geometry. The Zn(II) ion is coordinated by six N atoms from three ethyl-enediamine mol-ecules. The crystal structure displays weak hydrogen bonding between [SiF(6)](2-) anions and the ethyl-enediamine NH hydrogen atoms.

Tris(ethyl-enediamine)cobalt(II) sulfate.

Project description:The structure of the title compound, [Co(II)(C(2)H(8)N(2))(3)]SO(4), the cobalt example of [M(C(2)H(8)N(2))(3)]SO(4), is reported. The Co and S atoms are located at the 2d and 2c Wyckoff sites (point symmetry 32), respectively.
