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