摘要：

A redox reaction between MnO2, and MnCl2 occurs above 300-degrees-C in evacuate sealed tubes yielding the manganese oxychloride, Mn8O10Cl3. This compound is tetragonal with a = 9.255(3) angstrom, and c = 13.068(4) angstrom. The structural determination has been solved in the space group I4/mmm with Z = 4. (R = 0.029). Manganese 2+ are located in two symmetric sites, oxide cubes and chloride octahedra . Mn3+ ions occupy three octahedral sites, i.e. one undistorted oxygen octahedron and two highly distorted oxychloride octahedra. The chemical formulation is therefore better described as Mn2+Mn3+7O10Cl3.
