RbH2PO4 crystallizes in the tetragonal I-42d space group. Rb(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. P(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. H(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Rb(1), one P(1), and one H(1) atom.
RbH2PO4 crystallizes in the tetragonal I-42d space group. Rb(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. There are four shorter (3.00 Å) and four longer (3.13 Å) Rb(1)-O(1) bond lengths. P(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. All P(1)-O(1) bond lengths are 1.56 Å. H(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both H(1)-O(1) bond lengths are 1.21 Å. O(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Rb(1), one P(1), and one H(1) atom.
