BeRu2B crystallizes in the triclinic P1 space group. Be(1) is bonded in a 3-coordinate geometry to one Ru(2), two equivalent Ru(1), and one B(1) atom. The Be(1)-Ru(2) bond length is 2.03 Å. There is one shorter (2.05 Å) and one longer (2.55 Å) Be(1)-Ru(1) bond length. The Be(1)-B(1) bond length is 2.05 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 8-coordinate geometry to two equivalent Be(1), two equivalent Ru(2), and four equivalent B(1) atoms. There is one shorter (1.48 Å) and one longer (2.38 Å) Ru(1)-Ru(2) bond length. There are a spread of Ru(1)-B(1) bond distances ranging from 1.94-2.48 Å. In the second Ru site, Ru(2) is bonded in a 3-coordinate geometry to one Be(1), two equivalent Ru(1), and one B(1) atom. The Ru(2)-B(1) bond length is 1.48 Å. B(1) is bonded in a 2-coordinate geometry to one Be(1), one Ru(2), and four equivalent Ru(1) atoms.
