Ho(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(4), and four equivalent O(2) atoms. W(1) is bonded in a tetrahedral geometry to two equivalent O(3) and two equivalent O(4) atoms. P(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent K(1), one Ho(1), and one P(1) atom. In the second O site, O(2) is bonded in a 1-coordinate geometry to one K(1), two equivalent Ho(1), and one P(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to three equivalent K(1) and one W(1) atom.
