N2 - Soluble precursors possessing both Al-N and B-N backbones have been prepared from LiAlH 4, LiBH 4, and RNH 2· HCl (R = Me and Et) in one pot. The infrared (IR) and nuclear magnetic resonance (NMR) spectra of the precursors indicate that the precursors possess Al-H and B-H groups as well as Al-N, B-N, Al-(μ-H) 2-Al, and Al-(μ-H) 2-B bonds. TG analysis reveals that the ceramic yield of the precursor [AB11_Me (LiAlH 4/LiBH 4/MeNH 2·HCl = 1/1/2)] up to 1000°C under an argon atmosphere is 74.4 mass %. The transmission electron microscopic (TEM) images and the X-ray diffraction (XRD) pattern of AB11 Me that was pyrolyzed at 1600°C indicate that the average size of crystalline aluminum nitride (AlN) is about 14 nm and that crystalline AlN particles are distributed homogeneously in an amorphous matrix.
