MANGANESE OLIGOMER CONTAINING MAIN GROUP ELEMENTS

摘要

The present invention is based on the discovery that the previously disclosed tetranuclear manganese compounds are converted into a hexadeca manganese aggregate and a core of 4 barium, 2 sodium and chloride ion. Stated differently, one embodiment of the present invention comprises a composition of matter having the formula: ¢Mn16Ba8Na2ClO4(OH)4(CO3)4(H2O)22L8!?xH2O wherein x is an integer ranging from 0 to about 32 and L is a ligand having the formula: (I) Another embodiment of the present invention comprises a method of preparing the novel compounds of the present invention, which method comprises preparing an aqueous solution containing sodium chloride, a source of carbonate ion selected from sodium carbonate, sodium bicarbonate and mixtures thereof and a compound having the formula: Ba2¢Mn4(O)(OH)(O2CR)2L2! wherein R is hydrogen or a hydrocarbyl group and L is a ligand having formula I set forth above, and thereafter allowing the reaction mixture to stand for a time sufficient for a compound having the formula: ¢Mn16Ba8Na2ClO4(OH)4(CO3)4(H2O)22L8!?xH2O to form.
