Abstract:

A novel porous coordination polymer, iron naphthalenedicarboxylate Fe(OH)(1, 4-NDC)·2H₂O is hydrothermally synthesized by the reaction of FeSO₄·7H₂O and 1, 4-naphthalenedicarboxylic acid(1, 4-H₂NDC)at 150℃. The compound crystallizes in a tetragonal space group P4₂/nmc: a=2.1447(4)nm, c=0.68849(14)nm, V=3.1669(11)nm³, Z=8, R=0.0845, wR=0.1829. The crystal structure exhibits a three-dimensional framework which is composed of infinite chains of corner-sharing octahedral Fe(OH)₂O₄ with 1, 4-NDC ligands forming two types of channels with square-shaped cross-sections. The large channels present a cross-section of 0.76 nm×0.76 nm, while the small channels are about 0.30 nm×0.30 nm. No structural transformation occurs after removing the guest water molecules, while a robust structure generates with permanent porosity. The adsorption measurements show that the anhydrous sample of the compound can adsorb CO₂ into its pores. The adsorption isotherms for methanol, acetone, tetrahydrofuran and benzene are also measured.
