The material structure described by Mn2V2O7 crystallizes in the triclinic P1 space group. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(2), one O(3), one O(5), one O(6), and one O(7) atom to form VO5 trigonal bipyramids that share corners with two equivalent Mn(1)O6 octahedra and  an edgeedge with one Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 19-49°. In the second V site, V(2) is bonded in a 5-coordinate geometry to one O(1), one O(4), one O(5), one O(6), and one O(7) atom. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(6), and one O(7) atom to form distorted MnO6 octahedra that share corners with two equivalent V(1)O5 trigonal bipyramids and  an edgeedge with one V(1)O5 trigonal bipyramid. In the second Mn site, Mn(2) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(6), and one O(7) atom. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one V(2), one Mn(1), and one Mn(2) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one V(1), one Mn(1), and one Mn(2) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one V(1), one Mn(1), and one Mn(2) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one V(2), one Mn(1), and one Mn(2) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one V(1) and one V(2) atom. In the sixth O site, O(6) is bonded in a rectangular see-saw-like geometry to one V(1), one V(2), one Mn(1), and one Mn(2) atom. In the seventh O site, O(7) is bonded in a distorted trigonal pyramidal geometry to one V(1), one V(2), one Mn(1), and one Mn(2) atom. is represented by the CIF file [CIF]
