Be2Ru is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded to six equivalent Be(2) and six equivalent Ru(1) atoms to form a mixture of corner, face, and edge-sharing BeBe6Ru6 cuboctahedra. In the second Be site, Be(2) is bonded to two equivalent Be(1), four equivalent Be(2), and six equivalent Ru(1) atoms to form a mixture of corner, face, and edge-sharing BeBe6Ru6 cuboctahedra. Ru(1) is bonded in a 12-coordinate geometry to three equivalent Be(1) and nine equivalent Be(2) atoms.

In the first Be site, Be(1) is bonded to six equivalent Be(2) and six equivalent Ru(1) atoms to form a mixture of corner, face, and edge-sharing BeBe6Ru6 cuboctahedra. All Be(1)-Be(2) bond lengths are 2.17 Å. All Be(1)-Ru(1) bond lengths are 2.54 Å. In the second Be site, Be(2) is bonded to two equivalent Be(1), four equivalent Be(2), and six equivalent Ru(1) atoms to form a mixture of corner, face, and edge-sharing BeBe6Ru6 cuboctahedra. There are two shorter (2.13 Å) and two longer (2.20 Å) Be(2)-Be(2) bond lengths. There are two shorter (2.51 Å) and four longer (2.54 Å) Be(2)-Ru(1) bond lengths. Ru(1) is bonded in a 12-coordinate geometry to three equivalent Be(1) and nine equivalent Be(2) atoms.
