The structure described by Na2YbWPO8 is Esseneite-derived structured and crystallizes in the orthorhombic Ibca space group. Na(1) is bonded in a 6-coordinate geometry to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms. Yb(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(3), 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(4) is bonded in a 3-coordinate geometry to two equivalent Na(1) and one W(1) atom. In the second O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Yb(1), and one P(1) atom. In the third O site, O(2) is bonded in a 4-coordinate geometry to one Na(1), two equivalent Yb(1), and one P(1) atom. In the fourth O site, O(3) is bonded in a 2-coordinate geometry to one Na(1), one Yb(1), and one W(1) atom. is represented by the CIF card [CIF]
