Li Li Ag Ru
Li2RuAg crystallizes in the triclinic P1 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to one Li(2), two equivalent Ru(1), and two equivalent Ag(1) atoms. The Li(1)-Li(2) bond length is 1.52 Å. There is one shorter (1.96 Å) and one longer (2.99 Å) Li(1)-Ru(1) bond length. There is one shorter (2.93 Å) and one longer (3.08 Å) Li(1)-Ag(1) bond length. In the second Li site, Li(2) is bonded in a single-bond geometry to one Li(1), one Ru(1), and two equivalent Ag(1) atoms. The Li(2)-Ru(1) bond length is 1.15 Å. There is one shorter (2.93 Å) and one longer (3.08 Å) Li(2)-Ag(1) bond length. Ru(1) is bonded in a single-bond geometry to one Li(2), two equivalent Li(1), and two equivalent Ag(1) atoms. There is one shorter (2.70 Å) and one longer (2.72 Å) Ru(1)-Ag(1) bond length. Ag(1) is bonded to two equivalent Li(1), two equivalent Li(2), two equivalent Ru(1), and two equivalent Ag(1) atoms to form a mixture of distorted corner and edge-sharing AgLi4Ag2Ru2 hexagonal bipyramids. Both Ag(1)-Ag(1) bond lengths are 2.60 Å.
