Abstract:
A pair of zinc(II)-based one-dimensional (1D) homologous coordination polymers, [Zn(Hdba) 2 (bib)] n ( 1 ) and [Zn(Hdba) 2 (bmib)] n ( 2 ), where H 2 dba = 3-hydroxybenzoic acid, bib = 1,4-bis(1-imidazolyl)benzene, and bmib = 1,4-bis(2-methyl-1 H -imidazol-1-yl)benzene were hydrothermally synthesized and characterized through infrared spectroscopy (IR), elemental and thermal analysis (EA), powder X-ray diffraction (PXRD), and single-crystal X-ray diffraction (SCXRD) analyses. The results revealed that 1 and 2 have the same zigzag infinite chain framework through the partially deprotonated Hdba – monodentate linkage and with μ 2 -bib bridging the Zn(II) atoms in 1 , and with μ 2 -bmib bridges for the Zn(II) atoms in 2 . For both 1 and 2 , each zinc atom has a slightly twisted tetrahedral configuration with a N 2 O 2 donor set. These chains of 1 and 2 are further connected into three-dimensional (3D) supramolecular structures through O–H···O, C–H···O hydrogen bonds and π···π, C–H···π stacking interactions for 1 , and O–H···O, C–H···O hydrogen bonds for 2 . Topologically, the 3D hydrogen-bonded organic framework or the 2D π-stacking structure of 1 can be simplified as a 4-connected dia Diamond type with a Schläfli symbol {6 6 }, or as a 4-connected sql type with a Schläfli symbol {4 4 ·6 2 } and a Shubnikov tetragonal plane net. The thermal stability and the solid-state fluorescence properties of 1 and 2 were investigated.
