The molecular structures of M(CO)5Si6Me11 * 0.5 n-C5H12 (M = Mn, Re)

Abstract

The molecular structures of the transition metal cyclohexasilyl complexes M(CO)5Si6Me11 * 0.5 n-C5H12 (M = Mn, Re) were determined by single crystal X-ray diffraction. The two compounds are isomorphous. Their silicon-silicon bond lengths are compared with those of the parent cyclohexasilane and of other cyclohexasilyl complexes (comprising group 6, 7, 8, and 10 as well as row 3, 4, and 5 transition metals) with respect to silicon-silicon bond activation.
