Be2ReNi is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Be2ReNi clusters. Be(1) is bonded in a 3-coordinate geometry to one Be(1), one Re(1), and one Ni(1) atom. The Be(1)-Be(1) bond length is 1.02 Å. The Be(1)-Re(1) bond length is 1.45 Å. The Be(1)-Ni(1) bond length is 1.45 Å. Re(1) is bonded in a 3-coordinate geometry to two equivalent Be(1) and one Ni(1) atom. The Re(1)-Ni(1) bond length is 1.02 Å. Ni(1) is bonded in a 3-coordinate geometry to two equivalent Be(1) and one Re(1) atom.
