other. Voids between the one-dimensional chains are occupied by one nitrate counterion and two methanol molecules.
By mixing two equivalents of [G4 & H1] with only one equivalent of Zn
(NO 3 ) 2 Á(H 2 O) 6 in methanol, two-dimensional MOFs based on [2]rotaxane linkers
were obtained. Crystal analysis shows that the formula is [Zn(G4 & H1) 2 (H 2 O) 2 ]Á
