From a Monomeric Bismuth Silanolate to a Molecular Bismuth Oxo Cluster: [Bi₂₂O₂₆(OSiMe₂<i>t</i>Bu)₁₄]

Abstract

The high-nuclearity bismuth oxo cluster [Bi22O26(OSiMe2tBu)14] (see structure) was obtained by partial hydrolysis of Bi(OSiMe2tBu)3. A hydrophobic layer of silanolate groups covers the bismuth oxo core, the structure of which is closely related to that of β-Bi2O3. Both the bismuth oxo cluster and the bismuth silanolate precursor decompose to give the sillenite-type compound Bi12SiO20.
