MnPO4 is quartz (alpha)-derived structured and crystallizes in the trigonal P3_121 space group. Mn(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form MnO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with four equivalent Mn(1)O4 tetrahedra. There are two 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 distorted bent 150 degrees geometry to one Mn(1) and one P(1) atom.

Mn(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form MnO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. Both Mn(1)-O(1) bond lengths are 1.89 Å. Both Mn(1)-O(2) bond lengths are 1.96 Å. P(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with four equivalent Mn(1)O4 tetrahedra. Both P(1)-O(1) bond lengths are 1.55 Å. Both P(1)-O(2) bond lengths are 1.54 Å. There are two 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 distorted bent 150 degrees geometry to one Mn(1) and one P(1) atom.
