Abstract:
Four Zn II /Cd II coordination polymers (CPs) based on 2‐(4‐carboxy‐phenyl)imidazo[4, 5‐f]‐1, 10‐phenanthroline (HNCP) and different derivatives of 5‐ R ‐1, 3‐benzenedicarboxylate (5‐ R ‐1, 3‐BDC) ( R = NO 2 , H, OH), [Zn(HNCP)(5‐NO 2 ‐1, 3‐BDC)] n ( 1 ), [Cd(HNCP)(5‐NO 2 ‐1, 3‐BDC)] n ( 2 ), [Zn(HNCP)(1, 3‐BDC)(H 2 O) 2 ] n ( 3 ), and {[Zn(HNCP)(5‐OH‐1, 3‐BDC)(H 2 O) · H 2 O} n ( 4 ) were synthesized under hydrothermal conditions. Compounds 1 – 4 were determined by elemental analyses, IR spectroscopy, and single‐crystal and powder X‐ray diffraction. Compounds 1 and 2 are isomorphous, presenting a 4‐connected uninodal (4, 4)‐sql 2D framework with threefold interpenetration, which are further extended into the three‐dimensional (3D) supramolecular architecture through π ··· π stacking interactions between the aryl rings of 5‐NO 2 ‐1, 3‐BDC. Compared to compound 1 , 3 is obtained by using different reaction temperatures and metal‐ligand ratios, generating a 3D framework with –ABAB– fashion via π ··· π stacking interactions. Compound 4 is a 1D chain, which is further extended into a 3D supramolecular net by hydrogen bonds and π ··· π stacking interactions. The thermogravimetric and fluorescence properties of 1 – 4 were also explored.
