Phosphine complexes of main group elements: crystal structure of {Li[C(PMe2)3]-(tetrahydrofuran)}2

Abstract

The X-ray structure determination of the title compound, obtained by recrystallisation of LiC(PMe₂)₃ from pentane–tetrahydrofuran (thf) as colourless crystals, reveals it to be dimeric with two nearly planar (Me₂P)₃C-moieties linked by (thf)Li fragments via chelating and additional π-type interactions.
