Nb2OsB2 crystallizes in the tetragonal P4/mnc space group. Nb(1) is bonded in a 10-coordinate geometry to four equivalent Os(1) and six equivalent B(1) atoms. Os(1) is bonded in a 12-coordinate geometry to eight equivalent Nb(1) and four equivalent B(1) atoms. B(1) is bonded in a 9-coordinate geometry to six equivalent Nb(1), two equivalent Os(1), and one B(1) atom.
Nb2OsB2 crystallizes in the tetragonal P4/mnc space group. Nb(1) is bonded in a 10-coordinate geometry to four equivalent Os(1) and six equivalent B(1) atoms. There are two shorter (2.74 Å) and two longer (2.85 Å) Nb(1)-Os(1) bond lengths. There are a spread of Nb(1)-B(1) bond distances ranging from 2.42-2.49 Å. Os(1) is bonded in a 12-coordinate geometry to eight equivalent Nb(1) and four equivalent B(1) atoms. All Os(1)-B(1) bond lengths are 2.40 Å. B(1) is bonded in a 9-coordinate geometry to six equivalent Nb(1), two equivalent Os(1), and one B(1) atom. The B(1)-B(1) bond length is 1.90 Å.
