Using ab initio evolutionary methodology for crystal structure prediction, we have found two orthorhombic structures of Pmn2 1 and Cmc2 1 for potential superhard OsN, energetically much superior to the previously proposed NaCl-type and WC-type structures. The Pmn2 1 structure which consisted of dist
