title: New mimic of zeolite: heterometallic organic host framework accommodating inorganic cations.
abstract: Presented here is a heterometallic organic framework [Na(2)(H(2)O)(10)](n)[CuZn(4)(mu(3)-OH)(4)(btec)(2)](n).2nH(2)O (1, btec = 1,2,4,5-benzenetetracarboxylate) that incorporates mixed Cu(2+)-Zn(2+) 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 [SiO(4)] and [AlO(4)]) and one kind of inorganic-templating cation.
