[J. Mater. Chem., Vol.6, No.11, p.1799-1803, 1996]

A cubic BC2.5N solid solution was synthesized in 18% yield by shock-compression of a hexagonal BC2.5N layered compound. The cubic phase was confirmed to have a diamond structure without a long range order of atomic arrangement. The material is composed of microcrystals of 5-20nm in size. All constituent atoms are tetrahedrally coordinated, giving C-C, C-B, C-N, and B-N bonds.
