Crystallography of the Ru-B and Os-B Systems
Abstract
The Ru-B and Os-B systems were investigated by x-ray powder diffraction. In addition to Aronsson's hexagonal Ru7B3 phase, two new hexagonal Ru-B phases were found: RuB2(D6h1—P6/mmm, a0=2.852 A, c0=2.855 A) and Ru2B5(D6h4—P6/mmc, a0=2.89 A, c0=12.81 A. In the Os-B system, two new hexagonal phases, isomorphous with the latter Ru-B phases, were found: OsB2(a0=2.876 A, c0=2.871 A) and Os2B5 (a0=2.91 A, c0=12.91 A). RuB2 and OsB2 are isomorphous with MoB2; Ru2B5 and Os2B5 are isomorphous with W2B5.
