Syntheses, Crystal Structures, Luminescence, and Magnetic Properties of Two Coordination Polymers Derived From Semirigid 1‐Carboxymethyl‐3, 5‐Dimethyl‐1H‐Pyrazole‐4‐Carboxylic Acid

Abstract

AbstractAbstract. Two coordination polymers, namely, {[Cd(cdpc)(hmt)(H2O)]·H2O}n (1), and [Mn(Hcdpc)2(4, 4′‐bpy)(H2O)]n (2), were constructed by synergistic assembly through the mixed‐ligand synthetic strategy (H2cdpc = 1‐carboxymethyl‐3, 5‐dimethyl‐1H‐pyrazole‐4‐carboxylic acid, hmt = hexamethylenetetramine, and 4, 4′‐bpy = 4, 4′‐dipyridine). Their structures were determined by single‐crystal X‐ray diffraction analyses and further characterized by elemental analyses, IR spectra, powder X‐ray diffraction (PXRD), and thermogravimetric (TG) analyses. Single X‐ray diffraction analysis reveals that complex 1 is a 2D 4‐connected sql sheet, and complex 2 is an interesting 1D loop chain. The two complexes are further expanded to 3D supramolecular structure through non‐covalent bonds. Besides, luminescent properties of two complexes in the solid state and magnetic property of 2 were also investigated.
