Be Be Ru Cl
Be2RuCl crystallizes in the triclinic P1 space group. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a 5-coordinate geometry to one Be(2), two equivalent Ru(1), and two equivalent Cl(1) atoms. The Be(1)-Be(2) bond length is 1.47 Å. There is one shorter (2.30 Å) and one longer (2.55 Å) Be(1)-Ru(1) bond length. There is one shorter (1.91 Å) and one longer (2.21 Å) Be(1)-Cl(1) bond length. In the second Be site, Be(2) is bonded in a 5-coordinate geometry to one Be(1), two equivalent Ru(1), and two equivalent Cl(1) atoms. There is one shorter (1.91 Å) and one longer (2.21 Å) Be(2)-Ru(1) bond length. There is one shorter (2.30 Å) and one longer (2.55 Å) Be(2)-Cl(1) bond length. Ru(1) is bonded in a 6-coordinate geometry to two equivalent Be(1), two equivalent Be(2), and two equivalent Cl(1) atoms. There is one shorter (2.04 Å) and one longer (2.15 Å) Ru(1)-Cl(1) bond length. Cl(1) is bonded in a 6-coordinate geometry to two equivalent Be(1), two equivalent Be(2), and two equivalent Ru(1) atoms.
