The Fe3+ 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 Fe3+ has become a hot topic. A novel two‐dimensional ZnII coordination framework, poly[[μ‐4,4′‐bis(2‐methylimidazol‐1‐yl)diphenyl ether‐κ2N3:N3′](μ‐4,4′‐sulfonyldibenzoato‐κ2O:O′)zinc(II)], [Zn(C14H8O6S)(C20H18N4O)]n or [Zn(SDBA)(BMIOPE)]n, (I), where H2SDBA 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 44‐sql network. In addition, it displays a highly selective and sensitive sensing for Fe3+ ions in aqueous solution.

Semirigid organic ligands can adopt different conformations to construct coordination polymers with more diverse structures when compared to those constructed from rigid ligands. A new asymmetric semirigid organic ligand, 4-{2-[(pyridin-3-yl)methyl]-2H-tetrazol-5-yl}pyridine (L), has been prepared and used to synthesize three bimetallic macrocyclic complexes and one coordination polymer, namely, bis(μ-4-{2-[(pyridin-3-yl)methyl]-2H-tetrazol-5-yl}pyridine)bis[dichloridozinc(II)] dichloromethane disolvate, [Zn2Cl4(C12H10N6)2]·2CH2Cl2, (I), the analogous chloroform monosolvate, [Zn2Cl4(C12H10N6)2]·CHCl3, (II), bis(μ-4-{2-[(pyridin-3-yl)methyl]-2H-tetrazol-5-yl}pyridine)bis[diiodidozinc(II)] dichloromethane disolvate, [Zn2I4(C12H10N6)2]·2CH2Cl2, (III), and catena-poly[[[diiodidozinc(II)]-μ-4-{2-[(pyridin-3-yl)methyl]-2H-tetrazol-5-yl}pyridine] chloroform monosolvate], {[ZnI2(C12H10N6)]·CHCl3} n , (IV), by solution reaction with ZnX 2 (X = Cl and I) in a CH2Cl2/CH3OH or CHCl3/CH3OH mixed solvent system at room temperature. Complex (I) is isomorphic with complex (III) and has a bimetallic ring possessing similar coordination environments for both of the ZnII cations. Although complex (II) also contains a bimetallic ring, the two ZnII cations have different coordination environments. Under the influence of the I− anion and guest CHCl3 molecule, complex (IV) displays a significantly different structure with respect to complexes (I)–(III). C—H...Cl and C—H...N hydrogen bonds, and π–π stacking or C—Cl...π interactions exist in complexes (I)–(IV), and these weak interactions play an important role in the three-dimensional structures of (I)–(IV) in the solid state. In addition, the fluorescence properties of L and complexes (I)–(IV) were investigated.
