The trinuclear zinc siloxane [(MeZn) 2 Zn(OSiPh 3 ) 4 ] ( 1 ) and the first novel siloxane‐bridged hexanuclear dimer [{Me(THF)Zn} 2 OZn(OSiR 2 )(R 1 )] 2 (R = Ph, R 1 = OSiR 2 OSiR 2 O) ( 2 ) are accessible by Brønsted acid/base reaction of triorganosilanols with the zinc base ZnMe 2 . 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.
