Al In In Ru
RuIn2Al crystallizes in the triclinic P1 space group. Ru(1) is bonded in a 4-coordinate geometry to one In(2), two equivalent In(1), and three equivalent Al(1) atoms. The Ru(1)-In(2) bond length is 2.26 Å. There is one shorter (2.26 Å) and one longer (3.11 Å) Ru(1)-In(1) bond length. There are a spread of Ru(1)-Al(1) bond distances ranging from 2.73-3.04 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 5-coordinate geometry to two equivalent Ru(1), two equivalent In(2), and one Al(1) atom. There is one shorter (2.32 Å) and one longer (2.38 Å) In(1)-In(2) bond length. The In(1)-Al(1) bond length is 2.56 Å. In the second In site, In(2) is bonded in a 1-coordinate geometry to one Ru(1), two equivalent In(1), and one Al(1) atom. The In(2)-Al(1) bond length is 2.68 Å. Al(1) is bonded in a 5-coordinate geometry to three equivalent Ru(1), one In(1), and one In(2) atom.
