Mn2Zn(PO5)2 crystallizes in the orthorhombic Fddd space group. Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MnO6 octahedra that share corners with two equivalent Mn(1)O6 octahedra and corners with four equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 48°. Zn(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(3) atoms. P(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form PO4 tetrahedra that share corners with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-63°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Mn(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent Mn(1) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one Mn(1), one Zn(1), and one P(1) atom.
