Abstract
A method is provided for forming a zeolitic imidazolate framework composition using at least one reactant that is relatively insoluble in the reaction medium. Also provided herein is a material made according to the method, designated as EMM-19, and a method of using EMM-19 to adsorb gases, such as carbon dioxide.

A method for forming a zeolitic imidazolate framework composition, said method comprising the steps of:
- (a) mixing together a reaction medium, a source of a imidazolate or a substituted imidazolate reactant, IM, and a reactant source of metals M1 and M2 to form a synthesis mixture, wherein M1 and M2 comprise the same or different metal cations, at least one of which reactants is relatively insoluble in the reaction medium itself and in the synthesis mixture;
- and (b) maintaining the synthesis mixture having at least one relatively insoluble reactant under conditions sufficient to form a zeolitic imidazolate framework composition having a tetrahedral framework comprising a general structure, M1-IM-M2.
A method for forming a zeolitic imidazolate framework composition, said method comprising the steps of:
- (a) providing a liquid composition comprising a source of an imidazolate or a substituted imidazolate, IM, in a reaction medium;
- (b) providing a source of metals M1 and M2, wherein M1 and M2 comprise the same or different metal cations, at least one of which metals source(s) is a metal oxide that is relatively insoluble in the reaction medium and in the liquid composition;
- and (c) contacting the liquid composition with the source(s) of metals under conditions sufficient to produce a zeolitic imidazolate framework composition having a tetrahedral framework comprising a general structure, M1-IM-M2.
