A novel compound which can be used in the field of separation and purification of gases is disclosed. The compound can be incorporated into a silica gel incorporating polyazacycloalkane structural units for separating a predetermined gas from a mixture of gases. The mixture of gases is brought into contact with a metallated hybrid gel under conditions which make possible the absorption of the gas to be separated, followed by a phase of desorption of the attached gas, and the recovery of the gas.

The sol-gel process has been used to prepare new organicâinorganic hybrid materials with various textures from cyclam derivatives bearing four hydrolysable SiX3 groups (X = OEt, H) as well as from the corresponding CuII and CoII complexes of the cyclam derivative (X = OEt).
