- Institute of Functional Material Chemistry, Faculty of Chemistry, Northeast Normal University, Changchun 130024 (China)
Five novel Zn{sup II}-(pyridyl)imidazole derivative coordination polymers, [Zn(L){sub 2}] (1), [Zn{sub 2}(mu{sub 3}-OH)L(m-BDC)] (2), [Zn{sub 2}(mu{sub 3}-OH)L(p-BDC)].H{sub 2}O (3), [Zn{sub 2}L(BTC)(H{sub 2}O)].2.5H{sub 2}O (4) and [Zn{sub 3.5}(mu{sub 3}-OH)L{sub 2}(BTEC)(H{sub 2}O)].H{sub 2}O (5) (L=4-((2-(pyridine-2-yl)-1H-imidazol-1-yl)methyl)benzoic acid, p-H{sub 2}BDC=1,4-benzenedicarboxylic acid, m-H{sub 2}BDC=1,3-benzenedicarboxylic acid, H{sub 3}BTC=1,3,5-benzenetricarboxylic acid, H{sub 4}BTEC=1,2,4,5-benzenetetracarboxylic acid), were successfully synthesized under hydrothermal conditions through varying auxiliary aromatic-acid ligands and structurally characterized by X-ray crystallography. Compound 1 exhibits a 1D chain linked via double L bridges. Compound 2 features a well-known pcu topology with bent dicarboxylate ligand (m-H{sub 2}BDC) as an auxiliary ligand, while 3 displays a bcu network with linear dicarboxylate ligand (p-H{sub 2}BDC) as an auxiliary ligand. The structure of compound 4 is a novel 3D (3,5)-connected network with (4.6{sup 2})(4.6{sup 4}.8{sup 2}.10.12{sup 2}) topology. It is interesting that compound 5 shows an intricate (3,4,8)-connected framework with (4.6{sup 2})(4{sup 2}.6{sup 3}.8)(4{sup 2}.6{sup 4})(4{sup 2}.6{sup 18}.7.8{sup 6}.10) topology. In addition, their infrared spectra (IR), X-ray powder diffraction (XPRD) and photoluminescent properties were also investigated in detail. - Graphical abstract: Five novel Zn{sup II}-organic architectures have been hydrothermally synthesized through varying auxiliary aromatic-acid ligands and characterized by X-ray diffraction, the photoluminescence properties of compounds 1-5 were studied.
