Abstract: A new supermolecular compound, [C7H10N4][Mo8O26]0.5·H2O has been synthesized from 1,1-bis(imidazole) methane and (NH4)6Mo7O24·4H2O by hydrothermal method. Structural analysis reveals that every asymmetric structure unit of the compound is composed of one [C7H10N4]2+ and half [Mo8O26]4– and one water molecule. Crystal pack of the compound suggests that polyacid anions represent the one-dimensional chain-shaped structure and organic cations parallel the one-dimensional chains. The compound has the characteristics of detection Fe3+, adsorption and catalysis activities.
