Two 1D Ladderlike Heterometallic Zinc(II) Coordination Polymers: Syntheses, Crystal Structures, and Fluorescence Properties

Abstract

Abstract Two coordination polymers [Zn 2 (ipt) 2 (CuL) 2 (H 2 O)] ( 1 ) and [Zn 2 (ipt) 2 (NiL) 2 (H 2 O)] ( 2 ) ( M L, H 2 L = 2,3‐dioxo‐5,6,14,15‐dibenzo‐1,4,8,12‐tetraazacyclo‐pentadeca‐7,13‐dien; H 2 ipt = isophthalic acid) were synthesized by solvothermal methods and characterized by single‐crystal X‐ray diffraction. Complexes 1 and 2 exhibit ladderlike chains, consisting of Zn 4 Cu 4 and Zn 4 Ni 4 units, respectively, which are connected via oxamide and isophthalate. These chains are further interlinked by hydrogen bonds resulting in a 2D supramolecular architecture. The fluorescence properties of compounds 1 and 2 are also discussed.
