Patent ID: 8637690

Claim:
A crystallized hybrid material IM-19 with a mixed organic-inorganic matrix containing an inorganic network of gallium metal centers connected to each other by terephthalate organic ligands, having an X-ray diffraction diagram including at least the lines inscribed in the table below: 2 Theta (°) d hkl (Å) I/I 0 9.24 9.56 F 12.47 7.10 FF 17.68 5.01 f 18.12 4.89 ff 18.56 4.78 f 19.34 4.59 ff 20.62 4.30 ff 23.29 3.82 ff 24.73 3.60 ff 25.10 3.54 f 26.06 3.42 ff 26.83 3.32 ff 27.09 3.29 ff 27.50 3.24 ff 28.00 3.18 ff 29.25 3.05 ff 29.97 2.98 ff 30.11 2.97 ff 31.19 2.87 ff 31.33 2.85 ff 32.11 2.79 ff 33.78 2.65 ff 34.42 2.60 ff 34.91 2.57 ff 35.92 2.50 ff 36.36 2.47 ff 36.75 2.44 ff 37.83 2.38 ff 40.56 2.22 ff 41.82 2.16 ff 42.34 2.13 ff 42.65 2.12 ff 44.27 2.04 ff 44.78 2.02 ff 47.59 1.91 ff 47.90 1.90 ff 48.92 1.86 ff where FF = very high; F = high; m = medium; mf = medium low; f = low; ff = very low. Intensity I/I 0 is given with respect to a relative intensity scale where a value of 100 is assigned to the most intense line of the X-ray diffraction diagram: ff < 15; 15 ≦ f < 30; 30 ≦ mf < 50; 50 ≦ m < 65; 65 ≦ F < 85; FF ≧ 85.
