New mimic of zeolite: heterometallic organic host framework accommodating inorganic cations

Presented here is a heterometallic organic framework [Na2(H2O)10]n[CuZn4(μ3-OH)4(btec)2]n·2nH2O (1, btec = 1,2,4,5-benzenetetracarboxylate) that incorporates mixed Cu2+–Zn2+ oxide chains and accommodates Na+ cations as extraframework guest species; such a building mode is comparable to that of aluminosilicate zeolites where the porous framework combines two kinds of structural building units (such as [SiO4] and [AlO4]) and one kind of inorganic-templating cation.
