摘要

Four Zn-II/Cd-II coordination polymers (CPs) based on 2-(4carboxy- phenyl) imidazo[ 4,5-f]-1,10-phenanthroline (HNCP) and different derivatives of 5-R-1,3-benzenedicarboxylate (5-R-1,3BDC) (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)(H2O)(2)](n) (3), and {[ Zn(HNCP)(5-OH-1,3-BDC)(H2O) center dot H2O} 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 pi center dot center dot center dot pi stacking interactions between the aryl rings of 5-NO2-1,3-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 pi center dot center dot center dot pi stacking interactions. Compound 4 is a 1D chain, which is further extended into a 3D supramolecular net by hydrogen bonds and pi center dot center dot center dot pi stacking interactions. The thermogravimetric and fluorescence properties of 1-4 were also explored.
