The plane model of graphene layer of stereoisomers of carbon and boron nitride such as nanosize t-Ñã and t-BNã particles, which is perimetrically symmetric about main axis of the 63-degree is proposed. Comparative analysis of the geometric (by Slater) and force (by Allreds–Rokhow) parameters of chemical bonding in plane of sp2-hybridization of the inert surface and reactionary active perimeter of C atoms, pair of B and N atoms, and H and O atoms. Model has several levels such as: formation, ordering, perimetrical hydrolysis, dehydration, losses of stoichiometry by nitrogen, where B/N ? 1, fractal fragmentation symmetrically about third degree axis, and complete decomposition. Dependence of composition and average diameter of particles on degree of centrosymmetric macrocyclization of t-BNã particles is revealed. This dependence corresponds to positive integers. Qualitative experimental data of x-ray analysis, IR-spectrometry and t-BNã composition show close agreement within the framework of the presented model.
