Be2WRe crystallizes in the monoclinic Cm space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a 10-coordinate geometry to four equivalent Be(2), four equivalent W(1), and two equivalent Re(1) atoms. There are a spread of Be(1)-Be(2) bond distances ranging from 2.15-2.44 Å. There are a spread of Be(1)-W(1) bond distances ranging from 2.08-2.39 Å. There is one shorter (2.63 Å) and one longer (2.77 Å) Be(1)-Re(1) bond length. In the second Be site, Be(2) is bonded in a single-bond geometry to four equivalent Be(1), one W(1), and four equivalent Re(1) atoms. The Be(2)-W(1) bond length is 1.25 Å. There are a spread of Be(2)-Re(1) bond distances ranging from 2.86-3.09 Å. W(1) is bonded in a single-bond geometry to one Be(2), four equivalent Be(1), and four equivalent Re(1) atoms. There are a spread of W(1)-Re(1) bond distances ranging from 2.92-3.15 Å. Re(1) is bonded in a 14-coordinate geometry to two equivalent Be(1), four equivalent Be(2), four equivalent W(1), and four equivalent Re(1) atoms. All Re(1)-Re(1) bond lengths are 3.07 Å.
