Sn-flux syntheses, characterizations and bonding analyses of OsB and TiB2

Single-phase crystalline powder of the technologically important TiB2 and powder of OsB have been successfully synthesized at moderate temperature (900 °C) using metallic tin as a melting agent. The structural relationship between both phases is discussed. COHP bonding analyses show strong B–B interactions in TiB2 but no such in OsB. The bonding situation in both phases is also compared with that of Ti1.6Os2.4B2 and Ti1.6Os1.4RuB2 phases. TiB2 and OsB are metallic conductors according to DOS curves.
