Cr3Os crystallizes in the cubic Pm-3n space group. Cr(1) is bonded in a 6-coordinate geometry to two equivalent Cr(1) and four equivalent Os(1) atoms. Os(1) is bonded to twelve equivalent Cr(1) atoms to form a mixture of edge and face-sharing OsCr12 cuboctahedra.
Cr3Os crystallizes in the cubic Pm-3n space group. Cr(1) is bonded in a 6-coordinate geometry to two equivalent Cr(1) and four equivalent Os(1) atoms. Both Cr(1)-Cr(1) bond lengths are 2.31 Å. All Cr(1)-Os(1) bond lengths are 2.58 Å. Os(1) is bonded to twelve equivalent Cr(1) atoms to form a mixture of edge and face-sharing OsCr12 cuboctahedra.
