Abstract
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 1 chloride ion. Stated differently, one embodiment of the present invention comprises a composition of matter having the formula: EQU [Mn.sub.16 Ba.sub.8 Na.sub.2 ClO.sub.4 (OH).sub.4 (CO.sub.3).sub.4 (H.sub.2 O).sub.22 L.sub.8 ].multidot.xH.sub.2 O wherein x is an integer ranging from 0 to about 32 and L is a ligand having the formula: ##STR1## 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: EQU Ba.sub.2 [Mn.sub.4 (O)(OH)(O.sub.2 CR).sub.2 L.sub.2 ] 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: EQU [Mn.sub.16 Ba.sub.8 Na.sub.2 ClO.sub.4 (OH).sub…
