NaRu2O4 crystallizes in the orthorhombic Pnma space group. Na(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded to one O(3), two equivalent O(1), and three equivalent O(4) atoms to form a mixture of edge and corner-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles range from 45-54°. In the second Ru site, Ru(2) is bonded to one O(1), two equivalent O(3), and three equivalent O(2) atoms to form a mixture of edge and corner-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles range from 45-54°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to two equivalent Na(1), one Ru(2), and two equivalent Ru(1) atoms. In the second O site, O(2) is bonded to two equivalent Na(1) and three equivalent Ru(2) atoms to form a mixture of distorted edge and corner-sharing ONa2Ru3 square pyramids. In the third O site, O(3) is bonded to two equivalent Na(1), one Ru(1), and two equivalent Ru(2) atoms to form a mixture of distorted edge and corner-sharing ONa2Ru3 trigonal bipyramids. In the fourth O site, O(4) 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.
NaRu2O4 crystallizes in the orthorhombic Pnma space group. Na(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Both Na(1)-O(1) bond lengths are 2.49 Å. Both Na(1)-O(2) bond lengths are 2.34 Å. There is one shorter (2.56 Å) and one longer (2.63 Å) Na(1)-O(3) bond length. Both Na(1)-O(4) bond lengths are 2.37 Å. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded to one O(3), two equivalent O(1), and three equivalent O(4) atoms to form a mixture of edge and corner-sharing RuO6 octahedra.
