MnZnPO5 crystallizes in the monoclinic Cc space group. Mn(1) is bonded to one O(1), one O(2), one O(3), one O(4), and two equivalent O(5) 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 44°. Zn(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(4), and one O(5) atom. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share corners with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-43°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Mn(1), one Zn(1), and one P(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Mn(1), one Zn(1), and one P(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Mn(1), one Zn(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Mn(1), one Zn(1), and one P(1) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to two equivalent Mn(1) and one Zn(1) atom.
