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

Abstract

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.
