Na Na Na Ru Ru
Na3Ru2 crystallizes in the triclinic P1 space group. There are three inequivalent Na sites. In the first Na site, Na(1) is bonded in a 1-coordinate geometry to one Na(2), one Ru(1), and one Ru(2) atom. The Na(1)-Na(2) bond length is 1.55 Å. The Na(1)-Ru(1) bond length is 2.34 Å. The Na(1)-Ru(2) bond length is 1.74 Å. In the second Na site, Na(2) is bonded in a 5-coordinate geometry to one Na(1), two equivalent Ru(1), and two equivalent Ru(2) atoms. There is one shorter (2.76 Å) and one longer (3.54 Å) Na(2)-Ru(1) bond length. There is one shorter (2.40 Å) and one longer (3.01 Å) Na(2)-Ru(2) bond length. In the third Na site, Na(3) is bonded in a 4-coordinate geometry to one Ru(2) and three equivalent Ru(1) atoms. The Na(3)-Ru(2) bond length is 2.76 Å. There are a spread of Na(3)-Ru(1) bond distances ranging from 2.40-3.01 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 4-coordinate geometry to one Na(1), two equivalent Na(2), and three equivalent Na(3) atoms. In the second Ru site, Ru(2) is bonded in a 1-coordinate geometry to one Na(1), one Na(3), and two equivalent Na(2) atoms.
