摘要
A new structural model for the graphitic form of the carbonitride, C3N4, is proposed. This model is based on a new carbon vacancy order leading to an orthorhombic cell. The space group and the atomic positions are described. The experimental X-ray diffraction is indexed using this new model. (C) 1999 Elsevier Science Ltd. All rights reserved.
