Na La Ru Ru
NaLaRu2 crystallizes in the triclinic P1 space group. Na(1) is bonded in a 6-coordinate geometry to two equivalent La(1), two equivalent Ru(1), and two equivalent Ru(2) atoms. There is one shorter (2.56 Å) and one longer (2.70 Å) Na(1)-La(1) bond length. There is one shorter (2.56 Å) and one longer (2.70 Å) Na(1)-Ru(1) bond length. There is one shorter (2.26 Å) and one longer (2.54 Å) Na(1)-Ru(2) bond length. La(1) is bonded in a single-bond geometry to two equivalent Na(1) and one Ru(2) atom. The La(1)-Ru(2) bond length is 1.47 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one Ru(2) atom. The Ru(1)-Ru(2) bond length is 1.47 Å. In the second Ru site, Ru(2) is bonded in a 1-coordinate geometry to two equivalent Na(1), one La(1), and one Ru(1) atom.
