Si Ru Ru Br
Ru2SiBr crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one Ru2SiBr cluster. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 2-coordinate geometry to one Ru(2) and one Br(1) atom. The Ru(1)-Ru(2) bond length is 0.16 Å. The Ru(1)-Br(1) bond length is 0.29 Å. In the second Ru site, Ru(2) is bonded in a 2-coordinate geometry to one Ru(1), one Si(1), and one Br(1) atom. The Ru(2)-Si(1) bond length is 2.51 Å. The Ru(2)-Br(1) bond length is 0.29 Å. Si(1) is bonded in a 2-coordinate geometry to one Ru(2) and one Br(1) atom. The Si(1)-Br(1) bond length is 2.58 Å. Br(1) is bonded in a 2-coordinate geometry to one Ru(1), one Ru(2), and one Si(1) atom.
