Na2MnBSO7 crystallizes in the monoclinic P2_1/m space group. Na(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. Mn(1) is bonded to one O(2), one O(3), one O(5), one O(6), and two equivalent O(4) atoms to form MnO6 octahedra that share corners with four equivalent S(1)O4 tetrahedra. B(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. S(1) is bonded to one O(5), one O(6), and two equivalent O(4) atoms to form SO4 tetrahedra that share corners with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 36-45°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Na(1) and one B(1) atom. In the second O site, O(2) is bonded to two equivalent Na(1), one Mn(1), and one B(1) atom to form distorted edge-sharing ONa2MnB trigonal pyramids. In the third O site, O(3) is bonded to two equivalent Na(1), one Mn(1), and one B(1) atom to form distorted edge-sharing ONa2MnB tetrahedra. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Na(1), one Mn(1), and one S(1) atom. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Mn(1), and one S(1) atom. In the sixth O site, O(6) is bonded in a distorted bent 150 degrees geometry to one Mn(1) and one S(1) atom.
