OsPbSb crystallizes in the trigonal R3m space group. Os(1) is bonded in a hexagonal planar geometry to three equivalent Pb(1) and three equivalent Sb(1) atoms. All Os(1)-Pb(1) bond lengths are 2.69 Å. All Os(1)-Sb(1) bond lengths are 2.69 Å. Pb(1) is bonded to three equivalent Os(1) and four equivalent Sb(1) atoms to form PbSb4Os3 hexagonal pyramids that share corners with three equivalent Sb(1)Os3Pb4 hexagonal pyramids, corners with six equivalent Pb(1)Sb4Os3 hexagonal pyramids, edges with three equivalent Sb(1)Os3Pb4 hexagonal pyramids, and edges with six equivalent Pb(1)Sb4Os3 hexagonal pyramids. There are three shorter (2.75 Å) and one longer (3.13 Å) Pb(1)-Sb(1) bond length. Sb(1) is bonded to three equivalent Os(1) and four equivalent Pb(1) atoms to form SbOs3Pb4 hexagonal pyramids that share corners with three equivalent Pb(1)Sb4Os3 hexagonal pyramids, corners with six equivalent Sb(1)Os3Pb4 hexagonal pyramids, edges with three equivalent Pb(1)Sb4Os3 hexagonal pyramids, and edges with six equivalent Sb(1)Os3Pb4 hexagonal pyramids.
