Abstract
The FeIII ion as a ubiquitous metal plays a key role in biochemical processes. Iron deficiency or excess in the human body can induce various diseases. Thus, effective detection of the FeIII ion has been deemed an issue of focus. To develop more crystalline chemical sensors for the selective detection of Fe3+, two novel two-dimensional (2D) coordination polymers, namely, poly[[[μ-bis(pyridin-4-yl)amine-κ2N:N'](μ-naphthalene-2,6-dicarboxylato-κ2O2:O6)zinc(II)] 0.5-hydrate], {[Zn(C12H6O4)(C10H9N3)]·0.5H2O}n, 1, and poly[(4,4'-dimethyl-2,2'-bipyridine-κ2N,N')(μ-naphthalene-2,6-dicarboxylato-κ2O2:O6)hemi(μ-naphthalene-2,6-dicarboxylic acid-κ2O2:O6)copper(II)] [Cu(C12H6O4)(C12H12N2)(C12H8O4)0.5]n, 2, have been prepared using solvothermal methods. Single-crystal X-ray diffraction analysis shows that compound 1 is an undulating twofold interpenetrated 2D (4,4)-sql network and compound 2 is a twofold interpenetrated 2D honeycomb-type network with a (6,3)-hcb topology. In addition, 1 exhibits highly selective sensing for the Fe3+ ion.
