Abstract
The crystal chemistry of the B4C-type structures is described. New str uctural data for B12S, B13Se and B6O are presented. It is found that B 6O with a microhardness larger than that of B4C invariably contains a high concentration of vacancies at the oxygen position (B6O1-x with x in the range 0.76-0.84). Structural results for graphite-like phases i n the B-C-N system are presented and discussed.
