Patent number: 8889611
Abstract: The invention relates to compounds in solid form, containing a) one or more manganese complex compounds of the general formula (1), where M is independently selected from manganese in the III or IV oxidation state, X is independently a co-ordinating or bridging species selected from H2O, O22?, O2?, O2?, OH?, HO2?, SH?, S2?, SO, Cl?, N3?, SCN?, N3?, RCOO?, NH2? and NR3, where R is a radical selected from H, alkyl and aryl, L are independently organic ligands, each of which contains at least two nitrogen atoms co-ordinated on manganese, z is an integer from ?4 to +4, Y is a monovalent or multivalent counter-ion selected from chloride, sulphate, hydrogen sulphate, nitrate and acetate, which leads to charge neutrality of the complex, and q is an integer from 1 to 4, and b) one or more salts of the general formula R?—C6H4—SO3Me, where R? is CH3 or C2H5 and denotes Me, Na, K, Ca or Mg, characterized in that the molar ratio of the manganese complex compound of the general formula (1) to salt of the general formula R
