Polynuclear metal clusters, methods of making, and methods of use thereof
View Patent ↗Embodiments of the present disclosure provide for polynuclear manganese cluster compounds, methods of making, methods of use, method of producing hydrogen and oxygen from water, and the like.
1. A composition, comprising a polynuclear manganese cluster compound having oxygen-containing ligand, wherein the polynuclear manganese cluster compound has the formula Mn x M y R z , wherein R is an oxygen containing ligand, M is Ca or Sr, x is 2 to 84, y is 0 to 2, and z is 8 to 24, wherein each oxygen-containing ligand is independently selected from the group consisting of: an alcohol group, an alkoxide group, an ether group, and a combination thereof.
2. The composition of claim 1 , wherein the compound is dissolved in an aqueous solution.
3. The composition of claim 1 , wherein the polynuclear manganese cluster compound includes 2, 3, 4, 6, 8, 12, 13, and 14, to 84 manganese atoms.
4. The composition of claim 1 , wherein the oxygen-containing ligand is the alcohol group, wherein the alcohol group is represented by X(X′)(X″)—C—OH, wherein X, X′, and X″ are independently selected from the group consisting of: a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaryl group.
5. The composition of claim 1 , wherein the oxygen-containing ligand is the alkoxide group, wherein the alkoxide group is represented by X(X′)(X″)—C—O − , wherein X, X′, and X″ are independently selected from the group consisting of: a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaryl group.
6. The composition of claim 1 , wherein the oxygen-containing ligand is the ether group, wherein the ether group is represented by (X—O—X′) n , wherein n can be greater than 1 or 1 to 1000, wherein X and X′ are independently selected from the group consisting of: a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaryl group.
7. The composition of claim 1 , wherein the M is Ca or Sr and y is be 1 to 2.
8. The composition of claim 1 , wherein the polynuclear manganese cluster further comprises (H 2 O) groups.
