Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A novel bridging asymmetric benzimidazole ligand, 4‐{2‐[3‐(pyridin‐4‐yl)phenyl]‐1<italic>H</italic>‐benzimidazol‐1‐ylmethyl}benzoic acid, was used to construct three isomorphous two‐dimensional coordination polymers, namely <italic>catena</italic>‐poly[chlorido(μ₃‐4‐{2‐[3‐(pyridin‐4‐yl)phenyl]‐1<italic>H</italic>‐benzimidazol‐1‐ylmethyl}benzoato)zinc(II)], [Zn(C₂₆H₁₈N₃O₂)Cl]_{<italic>n</italic>}, (I), and the bromide, (II), and iodide, (III), analogues. Neighbouring two‐dimensional networks are stacked into three‐dimensional frameworks <italic>via</italic> interlayer π–π interactions. The luminescent properties of (I)–(III) were investigated and they display an obvious red‐shift in the solid state at room temperature.</p> </abstract>
