Arylene-bridged pentacoordinate siliconates 3-6 (arylene = 1,4-phenylene, 1,3-phenylene, 4,4′-biphenylene, and 9,10-anthracylene) were prepared from bis(triethoxysilyl)arylene precursors, catechol, and tri-ethylamine in tetrahydrofuran. 1,2-Ethylene and 1,6-hexylene-bridged pentacoordinate siliconates 7 and 8 were prepared from 1,2-bis(trimethoxysilyl)ethane and 1,6-bis(trimethoxysilyl)hexane, respectively. The molecular structure of the 1,4-phenylene-bridged siliconate 3 was determined by X-ray diffraction.
