Communication: BC4N, a new carbon material containing boron and nitrogen is formed in high yield by the thermal decomposition of pyridine–borane at 1050°C in argon. X-ray powder diffraction shows hk0 and 00l reflections indicating a turbostratic structure. X-ray photoelectron spectroscopy and analytical investigation in the transmission electron microscope reveal the random distribution of B[BOND]C, B[BOND]N, and C[BOND]C bonds present in the carbon residue.
