A new graphite-like layered material of composition BC6N2(H) is synthesized by the pyrolysis of (CH2CHCN)2: BCl3 adduct, which is prepared by the interaction of acrylonitrile with boron trichloride at room temperature. X-ray diffraction and UV-Visible spectroscopic analysis suggest that the adduct has a cubic or quasi-cubic structure and is gradually polymerized at room temperature. A possible arrangement in a layer of BC6N2 has been considered on the basis of ESCA spectra and chemical interactions among the starting materials, being composed of a unit structure N-C-C-C-C-C-C-N-B. BC6N1.5(H) film prepared by CVD reaction (CH2CHCN: BCl3=2:1) has a conductivity of 5.31×104S/m at room temperature and behaves as a semiconductor. The reduction of BC6N1.5(H) with Li+C10H8-/THF solution has yielded a lithium intercalated compound with a repeat distance of 0.87nm.
