Mn2CuH12(NO2)4 is Indium-like structured and crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of two Mn2CuH12(NO2)4 clusters. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form MnO4 tetrahedra that share  a cornercorner with one Cu(1)N4O2 octahedra. The corner-sharing octahedral tilt angles are 54°. In the second Mn site, Mn(2) is bonded to one O(5), one O(6), and two equivalent O(4) atoms to form MnO4 tetrahedra that share  a cornercorner with one Cu(1)N4O2 octahedra. The corner-sharing octahedral tilt angles are 48°. Cu(1) is bonded to two equivalent N(1), two equivalent N(2), one O(2), and one O(5) atom to form CuN4O2 octahedra that share  a cornercorner with one Mn(1)O4 tetrahedra and  a cornercorner with one Mn(2)O4 tetrahedra.
