The new compounds Mn2(OH)2SO3, Mn 2F(OH)SO3, and Mn5(OH)4(H 2O)2[SO3]2[SO4] were synthesized using a hydrothermal route and their crystal structures were determined using single crystal X-ray diffraction data. Mn2(OH) 2SO3 and Mn2F(OH)SO3 crystallized with the space group Pnma, a = 7.3580(14), b = 10.3429(20), c = 5.7611(11) Å, Z = 4; and a = 7.413(4), b = 10.139(5), c = 5.717(3) Å, Z = 4, respectively, whereas Mn5(OH)4(H2O) 2[SO3]2[SO4] crystallized with the space group P21/m, a = 7.6117(7), b = 8.5326(7), c = 10.9273(9) Å, β = 101.6005(13)°, Z = 2. Mn2(OH) 2SO3 and Mn2F(OH)SO3 consist of a 3D-framework of manganese octahedra sharing corners and edges and giving rise to 1D-tunnels along the a axis in which are located the sulfur atoms, whereas Mn5(OH)4(H2O)2[SO3] 2[SO4] consists of a 3D-framework of MnO5, MnO6, SO3, and SO4 polyhedra. Mn 5(OH)4(H2O)2[SO3] 2[SO4] is the first transition metal mixed sulfate-sulfite inorganic compound. Bent and symmetrically bifurcated hydrogen bonds were observed in these materials.
