KPO4 crystallizes in the monoclinic P2_1/m space group. K(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), and four equivalent O(3) atoms. P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one K(1) and one P(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to two equivalent K(1) and one P(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent K(1) and one P(1) atom.
KPO4 crystallizes in the monoclinic P2_1/m space group. K(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), and four equivalent O(3) atoms. The K(1)-O(1) bond length is 2.82 Å. Both K(1)-O(2) bond lengths are 3.21 Å. There are two shorter (2.85 Å) and two longer (2.96 Å) K(1)-O(3) bond lengths. P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), and two equivalent O(3) atoms. The P(1)-O(1) bond length is 1.55 Å. The P(1)-O(2) bond length is 1.54 Å. Both P(1)-O(3) bond lengths are 1.54 Å. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one K(1) and one P(1) atom.
