Rb2ZrO3 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Zr(1) is bonded to one O(2) and four equivalent O(1) atoms to form distorted edge-sharing ZrO5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to four equivalent Rb(1) and two equivalent Zr(1) atoms. In the second O site, O(2) is bonded in a 1-coordinate geometry to four equivalent Rb(1) and one Zr(1) atom.
Rb2ZrO3 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. There is one shorter (2.82 Å) and one longer (3.17 Å) Rb(1)-O(2) bond length. There are a spread of Rb(1)-O(1) bond distances ranging from 2.89-3.07 Å. Zr(1) is bonded to one O(2) and four equivalent O(1) atoms to form distorted edge-sharing ZrO5 trigonal bipyramids. The Zr(1)-O(2) bond length is 1.91 Å. There are two shorter (2.09 Å) and two longer (2.10 Å) Zr(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to four equivalent Rb(1) and two equivalent Zr(1) atoms. In the second O site, O(2) is bonded in a 1-coordinate geometry to four equivalent Rb(1) and one Zr(1) atom.
