The lithium silanolate LiOSiMe 3 is accessible from the reaction of Me 3 SiOSiMe 3 with LiMe in tetrahydrofuran. Single crystals of [Li 7 (OSiMe 3 ) 7 (THF)] were obtained from toluene at 25 °C. The structure of [Li 7 (OSiMe 3 ) 7 (THF)] ( C 2/ c ) features a capped trigonal antiprismatic arrangement of seven Li atoms. The Li atoms in [Li 7 (OSiMe 3 ) 7 (THF)] are μ 3 ‐bridged by seven O atoms of the silanolate ligand.
