The Fe 3+ ion is the most important element in environmental systems and plays a fundamental role in biological processes. Iron deficiency can result in diseases and highly selective and sensitive detection of trace Fe 3+ has become a hot topic. A novel two‐dimensional Zn II coordination framework, poly[[μ‐4,4′‐bis(2‐methylimidazol‐1‐yl)diphenyl ether‐κ 2 N 3 : N 3′ ](μ‐4,4′‐sulfonyldibenzoato‐κ 2 O : O ′)zinc(II)], [Zn(C 14 H 8 O 6 S)(C 20 H 18 N 4 O)] n or [Zn(SDBA)(BMIOPE)] n , (I), where H 2 SDBA is 4,4′‐sulfonyldibenzoic acid and BMIOPE is 4,4′‐bis(2‐methylimidazol‐1‐yl)diphenyl ether, has been prepared and characterized by IR, elemental analysis, thermal analysis and X‐ray diffraction analysis, the latter showing that the coordination polymer exhibits a threefold interpenetrating two‐dimensional 4 4 ‐ sql network. In addition, it displays a highly selective and sensitive sensing for Fe 3+ ions in aqueous solution.
