ZrV4Os crystallizes in the trigonal R3m space group. Zr(1) is bonded in a 9-coordinate geometry to three equivalent V(1), three equivalent V(2), and three equivalent Os(1) atoms. All Zr(1)-V(1) bond lengths are 3.15 Å. All Zr(1)-V(2) bond lengths are 2.90 Å. All Zr(1)-Os(1) bond lengths are 2.90 Å. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 2-coordinate geometry to one Zr(1), one V(2), two equivalent V(1), and two equivalent Os(1) atoms. The V(1)-V(2) bond length is 1.96 Å. Both V(1)-V(1) bond lengths are 1.13 Å. There is one shorter (2.39 Å) and one longer (2.88 Å) V(1)-Os(1) bond length. In the second V site, V(2) is bonded in a 9-coordinate geometry to three equivalent Zr(1), three equivalent V(1), and three equivalent Os(1) atoms. All V(2)-Os(1) bond lengths are 2.90 Å. Os(1) is bonded to three equivalent Zr(1), three equivalent V(2), and six equivalent V(1) atoms to form a mixture of corner and edge-sharing OsZr3V9 cuboctahedra.
