Tris(trifluoromethyl)germanium iodide as a new cross-linking agent in the synthesis of clathrochelates: monomeric mono- and binuclear iron(II) complexes formed by capping with germanium(IV)

Abstract

The first monomeric mono- and binuclear clathrochelates with trifluoromethylgermanium-containing capping groups have been prepared by template condensation of cyclohexanedion-1,2-dioxime, diacetylazineoxime and diacetylmonoxime hydrazone with IGe(CF 3) 3 on an Fe 2+ ion. The trigonal-antiprismatic geometry at the Fe 2+ coordination polyhedron for the complexes obtained has been established from 57Fe Mössbauer and UV spectra.
