Abstract
Two coordination polymers with 3D supramolecular network, {[Zn(L)(bpa) 0.5 (H 2 O) 2 ]·2.25H 2 O} n ( 1 ) and {[Cd(L)(H 2 O)]·2H 2 O} n ( 2 ) (H 3 LCl=5-(4-hydroxypyridinium-1-ylmethyl) isophthalic acid chloride, bpa=1, 2-bis(4-pyridyl)ethane) were hydrothermally synthesized and structurally characterized by X-ray diffraction analyses and further characterized by infrared spectra (IR), elemental analyses, and thermogravimetric (TG) analyses. Compound 1 exhibits a ladder-like chain structure, and such chains are further united together to generate a 3D supramolecular structure through the hydrogen bonding interactions. Compound 2 possesses a 2D coordination network with a 1D channel that run parallel to the coordination layers. Meanwhile, their luminescent properties have also been investigated in detail.CCDC:908522, 1 ;908526, 2 .
