BaMo(PO4)2 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded in a 10-coordinate geometry to four equivalent O(1) and six equivalent O(2) atoms. Mo(1) is bonded to two equivalent O(3) and four equivalent O(1) atoms to form MoO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form PO4 tetrahedra that share corners with three equivalent Mo(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 33-43°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Ba(1), one Mo(1), and one P(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one P(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Mo(1) and one P(1) atom.
BaMo(PO4)2 crystallizes in the monoclinic C2/m space group. Ba(1) is bonded in a 10-coordinate geometry to four equivalent O(1) and six equivalent O(2) atoms. All Ba(1)-O(1) bond lengths are 2.84 Å.
