The crystal structure described by OsCo3 is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. Os(1) is bonded to four equivalent Co(2) and eight equivalent Co(1) atoms to form OsCo12 cuboctahedra that share corners with four equivalent Os(1)Co12 cuboctahedra, corners with eight equivalent Co(2)Co8Os4 cuboctahedra, edges with eight equivalent Os(1)Co12 cuboctahedra, edges with sixteen equivalent Co(1)Co8Os4 cuboctahedra, faces with four equivalent Os(1)Co12 cuboctahedra, faces with six equivalent Co(2)Co8Os4 cuboctahedra, and faces with eight equivalent Co(1)Co8Os4 cuboctahedra. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to four equivalent Os(1), four equivalent Co(1), and four equivalent Co(2) atoms to form CoCo8Os4 cuboctahedra that share corners with twelve equivalent Co(1)Co8Os4 cuboctahedra, edges with eight equivalent Os(1)Co12 cuboctahedra, edges with eight equivalent Co(1)Co8Os4 cuboctahedra, edges with eight equivalent Co(2)Co8Os4 cuboctahedra, faces with four equivalent Os(1)Co12 cuboctahedra, faces with four equivalent Co(2)Co8Os4 cuboctahedra, and faces with ten equivalent Co(1)Co8Os4 cuboctahedra. In the second Co site, Co(2) is bonded to four equivalent Os(1) and eight equivalent Co(1) atoms to form CoCo8Os4 cuboctahedra that share corners with four equivalent Co(2)Co8Os4 cuboctahedra, corners with eight equivalent Os(1)Co12 cuboctahedra, edges with eight equivalent Co(2)Co8Os4 cuboctahedra, edges with sixteen equivalent Co(1)Co8Os4 cuboctahedra, faces with four equivalent Co(2)Co8Os4 cuboctahedra, faces with six equivalent Os(1)Co12 cuboctahedra, and faces with eight equivalent Co(1)Co8Os4 cuboctahedra. is represented by the CIF card [CIF]
