The sample was prepared as indicated in ref Q. Zhang, Z.C. Qin, J. Zhu, Philos. Mag. Lett. 80 (2000) 585. The analysis was performed in different areas of the sample. A new crystalline structure of orthorhombic type with a stoichiometry close to CN was determined using EELS, HREM and electron difraction. Analyst: Susana Trasobares. Temperature: Room.
