Sr Al Ru
SrRuAl is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrRuAl cluster. Sr(1) is bonded in a distorted single-bond geometry to one Ru(1) atom. The Sr(1)-Ru(1) bond length is 2.01 Å. Ru(1) is bonded in a distorted bent 120 degrees geometry to one Sr(1) and one Al(1) atom. The Ru(1)-Al(1) bond length is 0.83 Å. Al(1) is bonded in a single-bond geometry to one Ru(1) atom.
