2103370 9220444 PCTABS00017 Briefly stated, this present invention passes a new class of microporous zinc phosphorous oxide and zinc arsenic oxide compositions and method of preparation. The novel compositions have an oxide framework containing zinc and an oxide selected from the group consisting of phosphorous oxides, arsenic oxides and mixtures thereof as the sole lattice constituents; specifically the compositions have the formula: [Ma(R4X)b] [ZnpOq][(TO4-e)(OH)e]yLf .gH2O (I) where M is selected from the group consisting of H, Li, Na, K, Rb, Cs, Tl, Mg, Ca, Sr, Ba, and mixtures thereof; R is selected from the group consisting of H, alky groups having about 1 to about 8 carbon atoms, preferably about 1 to about 4 carbon atoms, and mixtures thereof; X is selected from the group consisting of N, P, As, and mixtures thereof; T is selected from the group consisting of P, As, and mixtures thereof; L is a halogen, and mixtures thereof; a, b, g, q, f are numerical values of from 0 to 200; p and y are numerical values greater than 0 up to about 200; and e is any numerical value from 0 to 4; provided that, when M is K and y is 2, e is not 1/2.
