Compound 1, synthesized at 90 °C, has a two-dimensional (2D) sheet structure, while 2 and 3, synthesized at 120 and 160 °C, respectively, have three-dimensional (3D) structures. Compound 2 has alternating hydrophobic and hydrophilic channels with pore dimensions ∼4.3 × 4.4 Å2 and ∼5.6 × 6.2 Å2, respectively. Compound 3 has only one type of pore with dimensions of ∼5.3 × 6.2 Å2. All three compounds have eight connected Zn3(RCOO)8 nodes as building units and are anionic, with dimethyl ammonium cations present inside the channels to balance charge. Compounds 1, 2, and 3 are supramolecular isomers with general formula [Zn1.5(FDA)2(Me2NH2)]n. %I ACS Publications
