Abstract

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 = NO2, H, OH), [Zn(HNCP)(5‐NO2 ‐1, 3‐BDC)] n (1 ), [Cd(HNCP)(5‐NO2 ‐1, 3‐BDC)] n (2 ), [Zn(HNCP)(1, 3‐BDC)(H2 O)2 ] n (3 ), and {[Zn(HNCP)(5‐OH‐1, 3‐BDC)(H2 O)· H2 O} n (4 ) were synthesized under hydrothermal conditions. Compounds1 –4 were determined by elemental analyses, IR spectroscopy, and single‐crystal and powder X‐ray diffraction. Compounds1 and2 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‐NO2 ‐1, 3‐BDC. Compared to compound1, 3 is obtained by using different reaction temperatures and metal‐ligand ratios, generating a 3D framework with –ABAB– fashion via π··· π stacking interactions. Compound4 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 of1 –4 were also explored. Abstract :
