Na(RuO2)4 crystallizes in the tetragonal I4/m space group. Na(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. Ru(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of edge and corner-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Na(1) and three equivalent Ru(1) atoms to form a mixture of distorted edge and corner-sharing ONa2Ru3 trigonal bipyramids. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent Ru(1) atoms.
Na(RuO2)4 crystallizes in the tetragonal I4/m space group. Na(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. All Na(1)-O(1) bond lengths are 2.82 Å. Ru(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of edge and corner-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles are 53°. There is one shorter (2.05 Å) and two longer (2.07 Å) Ru(1)-O(1) bond lengths. There is one shorter (1.95 Å) and two longer (1.99 Å) Ru(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Na(1) and three equivalent Ru(1) atoms to form a mixture of distorted edge and corner-sharing ONa2Ru3 trigonal bipyramids. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent Ru(1) atoms.
