IM-21 organic-inorganic hybrid solid and process for preparing same

摘要

A novel crystalline hybrid solid with a mixed organic-inorganic matrix is described which has a three-dimensional structure containing an inorganic framework with metallic centers based on zinc connected together via deprotonated organic ligands constituted by the entity —O2C—C6H2—(O)2—CO2. This novel solid is termed IM-21 and has an X-ray diffraction diagram as given below.

1. An IM-21 crystalline hybrid solid with a mixed organic-inorganic matrix, having a three-dimensional structure, containing an inorganic framework of metallic centers based on zinc connected together via deprotonated organic ligands constituted by the entity —O2C—C6H2(O)2—CO2—, said solid having an X-ray diffraction diagram including at least the lines entered in the table below:2θ (°)I/I0dhkl (Å)7.66s11.5311.96w7.3913.29w6.6614.22m6.2315.35m5.7718.39w4.8219.50w4.5520.15w4.4020.36w4.3622.36w3.9722.75w3.9123.11mw3.8424.04w3.7024.91w3.5727.57w3.2327.87mw3.2029.70w3.0132.66w2.7433.75w2.6534.65w2.5936.89w2.4437.26w2.4137.97w2.3738.55w2.3338.79w2.3239.60w2.2840.96w2.2041.30w2.1843.46w2.0844.31w2.04where s=strong; m=medium; mw=medium weak; w=weak,
the relative intensity I/I0 being given using a relative intensity scale whereby a value of 100 is attributed to the most intense peak of the X-ray diffraction diagram: w<15; 15≦mw<30; 30≦m<85; s≧85.
