The material described by MnPO4 is quartz (alpha)-derived structured and crystallizes in the trigonal R3 space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), one O(3), one O(5), and one O(7) atom to form distorted MnO4 tetrahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with two equivalent P(2)O4 tetrahedra. In the second Mn site, Mn(2) is bonded to one O(2), one O(4), one O(6), and one O(8) atom to form MnO4 tetrahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with two equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(3), and one O(8) atom to form PO4 tetrahedra that share corners with two equivalent Mn(1)O4 tetrahedra and corners with two equivalent Mn(2)O4 tetrahedra. In the second P site, P(2) is bonded to one O(4), one O(5), one O(6), and one O(7) atom to form PO4 tetrahedra that share corners with two equivalent Mn(1)O4 tetrahedra and corners with two equivalent Mn(2)O4 tetrahedra. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Mn(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Mn(2) and one P(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Mn(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Mn(2) and one P(2) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Mn(1) and one P(2) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one Mn(2) and one P(2) atom. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one Mn(1) and one P(2) atom. In the eighth O site, O(8) is bonded in a bent 120 degrees geometry to one Mn(2) and one P(1) atom. is represented by the CIF file [CIF]
