Embodiment Construction
[0021]The present invention provides new isostructural compounds having the general formula AnMmM′nO2n+m where A is an alkali metal, such as lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) or the transition metals silver (Ag) or thallium (TI) and mixtures thereof, M is lead (Pb), tin (Sn), germanium (Ge), calcium (Ca), strontium (Sr), barium (Ba), any divalent transition metal or mixtures thereof, M′ is bismuth (Bi), antimony (Sb) or mixtures thereof, and Q is sulfur (S), selenium (Se), or tellurium (Te) and mixtures thereof.
[0022]The variables n and m can be any number greater than zero. Preferably, n and m are integers. While the variables n and m can theoretically be any integer, preferably, n and m are between 1 and 20. Additionally, the ratio of cations to anions present in the compounds of the present invention will preferably be 1:1.
[0023]The compounds of the present invention can be synthesized utilizing at least two different groups of starting material...
