The new compound Co5(OH)6(H2O)2[SO3]2 was synthesized by a hydrothermal route and its crystal structure was determined from the combination of single crystal X-ray- and neutron powder-diffraction data. Co5(OH)6(H2O)2[SO3]2 crystallizes with the space group P21/c, a=7.0229(19) Å, b=5.4722(15) Å, c=15.833(4), β=106.34(1)°, V=583.9(3) Å3 and Z=4. The crystal structure consists of a 2D-framework of cobalt octahedra sharing corners and edges and giving rise to a stairs-like layers, interconnected through O-H⋯O-S4+ hydrogen bonds.
