A hyperhalogen is a superhalogen-containing composition in which the electron affinity (EA) of the hyperhalogen is even larger than that of the superhalogens they are composed of. Novel production methods are provided in which highly electronegative species are produced by surrounding a central metal atom by superhalogen moieties. ## Claims ### Claim 1 A hyperhalogen, comprising: a metal core; at least one superhalogen associated with said metal core, wherein the hyperhalogen composition has an EA higher than an EA of the at least one superhalogen included therein. ### Claim 2 (depends on 1) The hyperhalogen of claim 1, wherein the at least one superhalogen includes a plurality of superhalogens which may be the same or different and each of which is associated with said metal. ### Claim 3 (depends on 2) The hyperhalogen of claim 2 wherein the hyperhalogen has an EA higher than an EA of any superhalogen included therein. ### Claim 4 (depends on 2) The hyperhalogen of claim 2, wherein the EA of the hyperhalogen is at least 1 eV higher than the EA of the at least one superhalogen. ### Claim 5 (depends on 1) The hyperhalogen of claim 1 wherein said metal core is Au-based. ### Claim 6 (depends on 1) The hyperhalogen of claim 1 wherein said metal core is Cu-based. ### Claim 7 An electronegative composition comprising BO2 and having an EA of substantially greater than 4.32 eV. ### Claim 8 (depends on 7) The electronegative composition of claim 7, wherein the EA is 5.54 eV. ### Claim 9 A stable ternary nanocluster comprising superhalogen units as blocking blocks, wherein the nanocluster has an electron affinity larger than an electron affinity of any superhalogen making up the nanocluster. ### Claim 10 (depends on 9) The stable ternary nanocluster of claim 9 further comprising a central metal core. ### Claim 11 (depends on 10) The composition of claim 10, wherein the central metal core is Au or Cu. ### Claim 12 (depends on 1) The composition of claim 1, formulated in a product selected from the group consisting of a disinfectant, an air cleaner and a mood enhancer. ### Claim 13 A method of obtaining an increased EA for a superhalogen building block, comprising: substituting the superhalogen building block for an oxygen atom contained in a cluster to produce a hyperhalogen that has an EA of at least 1 eV greater than the EA of the superhalogen building block. ### Claim 14 (depends on 13) The method of claim 13, wherein the superhalogen building block is BO2. ### Claim 15 A method of producing a compound with high-EA, comprising: providing a starting material that includes at least one oxygen atom, substituting a superhalogen for an oxygen atom in the starting material, wherein one oxygen or plural oxygen atoms may be replaced, to produce the compound with high-EA. ### Claim 16 (depends on 15) The method of claim 15, wherein the produced compound with high-EA has an EA greater than an EA of the starting material. ### Claim 17 A composition comprising Au(BO2)2 or a derivative thereof. ### Claim 18 A composition comprising Au3O(BO2) or a derivative thereof. ### Claim 19 A composition comprising Cu((BO2)2 or a derivative thereof.
