V4Os crystallizes in the orthorhombic Fmmm space group. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 2-coordinate geometry to two equivalent V(2) and two equivalent Os(1) atoms. In the second V site, V(2) is bonded in a distorted body-centered cubic geometry to two equivalent V(1) and six equivalent V(2) atoms. Os(1) is bonded in a 4-coordinate geometry to four equivalent V(1) atoms.
V4Os crystallizes in the orthorhombic Fmmm space group. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 2-coordinate geometry to two equivalent V(2) and two equivalent Os(1) atoms. Both V(1)-V(2) bond lengths are 2.54 Å. Both V(1)-Os(1) bond lengths are 2.58 Å. In the second V site, V(2) is bonded in a distorted body-centered cubic geometry to two equivalent V(1) and six equivalent V(2) atoms. There are two shorter (2.54 Å) and four longer (2.67 Å) V(2)-V(2) bond lengths. Os(1) is bonded in a 4-coordinate geometry to four equivalent V(1) atoms.
