BeTc2Ru is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BeTc2Ru clusters. Be(1) is bonded in an L-shaped geometry to two equivalent Tc(1) atoms. Both Be(1)-Tc(1) bond lengths are 0.64 Å. Tc(1) is bonded in an L-shaped geometry to one Be(1) and one Ru(1) atom. The Tc(1)-Ru(1) bond length is 0.64 Å. Ru(1) is bonded in an L-shaped geometry to two equivalent Tc(1) atoms.
