The compound described by Nb3Os crystallizes in the cubic Pm-3n space group. Nb(1) is bonded in a 6-coordinate geometry to two equivalent Nb(1) and four equivalent Os(1) atoms. Os(1) is bonded to twelve equivalent Nb(1) atoms to form a mixture of face and edge-sharing OsNb12 cuboctahedra. is represented by the CIF card [CIF]
