摘要
Two coordination polymers of cadmium with formula [Cd(pyp)(2)(H2O)(2)](n) (1) and {[Cd-2(pyzca)(3)(atr) (H2O)]center dot H2O}(n) (2) [pypH = 3-pyridinepropionic acid, pyzcaH = 2-pyrazinecarboxylic acid and atrH = 5-aminotetrazole] have been synthesized and structurally characterized by X-ray single crystal diffraction analysis. Both complexes display 2D structures that extend into a 3D network by means of hydrogen bonding. The crystal packing of both complexes is reinforced by pi-pi interactions between adjacent aromatic rings. The fluorescence study indicates intraligand pi-pi* charge transfer, which is the reason for emission in both the complexes. (c) 2010 Elsevier B. V. All rights reserved.
