Abstract
The reaction of the fluorenyl alkali metals with the tridentate Lewis base diethyleneglycol–dimethylether (DIGLYME) yielded the compounds [Li(DIGLYME) 2]Fl ( 1, Fl=fluorenide anion), [Na(DIGLYME) 2]Fl ( 2), [KFl(DIGLYME)] 3 ( 3), [RbFl(DIGLYME)] 9 ( 4), [CsFl(DIGLYME)] 9 ( 5), [NaFl(DIGLYME)] 2 ( 6), and [(KFl) 2DIGLYME] n ( 7). The solid state structures of all complexes were determined by X-ray single crystal structure analysis. According to the X-ray analyses, the compounds 1 and 2 crystallize as solvent separated ion pairs, the complexes 3, 4, 5, and 6 as aggregates built up by two, three, or nine MFl(DIGLYME) units, and compound 7 as a polymeric band.
