Materials Data on B3Os2 by Materials Project
Os2B3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Os+1.50- is bonded in a 7-coordinate geometry to seven B1+ atoms. There are four shorter (2.21 Å) and three longer (2.22 Å) Os–B bond lengths. There are two inequivalent B1+ sites. In the first B1+ site, B1+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent Os+1.50- atoms. In the second B1+ site, B1+ is bonded to six equivalent Os+1.50- atoms to form distorted edge-sharing BOs6 pentagonal pyramids.
