NaPr2RuO6 crystallizes in the monoclinic P2_1/c space group. Na(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form NaO6 octahedra that share corners with six equivalent Ru(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-39°. Pr(1) is bonded in a 8-coordinate geometry to two equivalent O(2), three equivalent O(1), and three equivalent O(3) atoms. Ru(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form RuO6 octahedra that share corners with six equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-39°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Na(1), three equivalent Pr(1), and one Ru(1) atom. In the second O site, O(2) is bonded to one Na(1), two equivalent Pr(1), and one Ru(1) atom to form distorted corner-sharing ONaPr2Ru trigonal pyramids. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Na(1), three equivalent Pr(1), and one Ru(1) atom.
