Abstract
One embodiment of the present invention is based on the discovery of another hexadecanuclear manganese aggregate having a core of 6 barium ions surrounding a carbonate ion. Stated differently, one embodiment of the present invention comprises a composition of matter having the formula: EQU [Mn.sub.16 Ba.sub.10 O.sub.4 (OH).sub.4 (CO.sub.3).sub.5 L.sub.8 ].xH.sub.2 O wherein x is an integer ranging from about 0 to about 120 and L is a ligand. Another embodiment of the present invention comprises a method of preparing the novel compounds of the present invention, which method comprises preparing a chloride free aqueous solution containing a source of carbonate ion selected from sodium carbonate, CO.sub.2 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 ].xH.sub.2 O wherein R is hydrogen or a hydrocarbyl group, x is an integer ranging from 0 to about 30, 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.10 O.sub.4 (OH).sub.4 (CO.sub.3).sub.5 L.sub.8 ].xH.sub.2 O to form. The compounds of t…
