Abstract

The trinuclear zinc siloxane [(MeZn)2Zn(OSiPh3)4] (1) and the first novel siloxane-bridged hexanuclear dimer [{Me(THF)Zn}2OZn(OSiR2)(R1)]2 (R = Ph, R1 = OSiR2OSiR2O) (2) are accessible by Brønsted acid/base reaction of triorganosilanols with the zinc base ZnMe2. Both compounds were characterised by NMR spectroscopy and a single-crystal X-ray structure analysis. The X-ray structures of the reported complexes are discussed. (© Wiley-VCH Verlag GmbH & Co.
