The Fe^III 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 Fe^III 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.
