Abstract
The structural properties of three-dimensional ordered phases of (Formula presented)B and (Formula presented)B compounds were studied using the ab initio pseudopotential method. Two different stacking sequences, BC and BB, of graphite layers were considered. Results indicate that for (Formula presented)B, the structure with hexagonally symmetric distribution of B atoms and BC stacking is stable, whereas for (Formula presented)B, both BC and BB stackings are possible with BC stacking being more stable. In the case of (Formula presented)B, the interlayer spacing is 3.43-3.45 Å, while for (Formula presented)B, the interlayer spacing is 3.00 Å.
