摘要：

MnBr2 reacts with MnO2 in a temperature range of 300 - 500-degrees-C to Produce a new manganese oxybromide. Chemical analysis and structural determination indicate that the oxybromide possesses a chemical formula, Mn7.5O10Br3, which is different from the manganese oxychloride. The symmetry Is tetragonal with a = 9.327(5) angstrom and c = 13.104 (3) angstrom. The structure has been solved in the space group 14/mmm with Z = 4, R = 0.046. The oxybromide appears as a lacunar equivalent of Mn8O10Cl3 with empty Br6 octahedra.
