A Star-Shaped Heptanuclear Tetramine Cadmium(II) Complex

Abstract

Colourless rhombohedral crystals of dodekakis[tris(2-aminoethyl)amine]heptacadmium(II) tetradecaperchlorate, [Cd7(tren)12](ClO4)14, form from aqueous solutions of the cellulose solvent `Cd–tren' on addition of perchloric acid. The heptanuclear cations are flat star-shaped disks and are composed of Cd(tren) moieties that are linked by further tren ligands, which exhibit the unusual μ3,κ3N,N′,N′′ mode of coordination.
