Metal Hydroborates and Hydroborato Metalates, 21. Solvates of Lithium (Dimethylamino)trihydroborate

Li(Me2NBH3) (1) was prepared by deprotonation of Me2NH*BH3 with LiBu and its solubility determined in various solvents.Compound 1 is unstable in most etheral solvents and decomposes in a reversible reaction into LiH and Li(Me2N-BH2-NMe2-BH3) (2).Five solvates of 1 were characterised by X-ray structure analysis.Li(Me2NBH3)*TMEDA is a dimer in the solid state, and two units are connected to one another by B-H...Li bonds.The crystal structure of Li(Me2NBH3)*0.5 dioxane is represented by layers consisting of tetrameric Li(Me2NBH3) units connected via dioxane molecules.Each Li atom is coordinated to one oxygen atom, one nitrogen atom, and two hydrogen atoms.Also Li(Me2NBH3)*0.5 O2C3H6 forms an extended layer, however with pentacoordinated Li atoms which bear one oxygen, one nitrogen, and three hydrogen atoms.A similar layer structure was also found for Li(Me2NBH3)*O3C3H6 where each Li atom is bound to two oxygen atoms of different trioxane molecules, one nitrogen atom, and two hydrogen atoms.Finally, Li(Me2NBH3)*12-crown-4 retains its molecular integrity in the solid state.Its Li atom is pentacoordinated by four oxygen atoms and one nitrogen atom. - Keywords: Borate lithium (dimethylamino)trihydrido- / TMEDA complex / Dioxane complex / 12-Crown-4 complex
