Na3Ru crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a distorted trigonal planar geometry to three equivalent Ru(1) atoms. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to four equivalent Ru(1) atoms. Ru(1) is bonded in a 10-coordinate geometry to four equivalent Na(2) and six equivalent Na(1) atoms.
Na3Ru crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a distorted trigonal planar geometry to three equivalent Ru(1) atoms. There is one shorter (3.04 Å) and two longer (3.05 Å) Na(1)-Ru(1) bond lengths. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to four equivalent Ru(1) atoms. There are two shorter (3.22 Å) and two longer (3.29 Å) Na(2)-Ru(1) bond lengths. Ru(1) is bonded in a 10-coordinate geometry to four equivalent Na(2) and six equivalent Na(1) atoms.
