The structure described by Na2Tb(MoO4)(PO4) crystallizes in the orthorhombic Ibca space group. Na(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(4) atoms. Tb(1) is bonded in a 8-coordinate geometry to two equivalent O(3), two equivalent O(4), and four equivalent O(2) atoms. Mo(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(3) atoms. P(1) is bonded in a tetrahedral geometry to two equivalent O(2) and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Na(1) and one Mo(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Tb(1) and one P(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Tb(1) and one Mo(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Tb(1), and one P(1) atom. is represented by the CIF card [CIF]
