Özet

Four coordination polymers based on a new 3,5-dicarboxy-1-(4-cyanobenzyl)pyridin-1-ium bromide (H(2)cbpyBr), formulated as {[Mn(mu-cbpy)(2)]center dot 2H(2)O}(n) (1), {[Co(mu-cbpy)(2)]center dot 2H(2)O}n (2), {[Cu(mu-cbpy)(2)]center dot H2O}(n) (3) and {[Zn-3(mu-cbpy)6]center dot 6H(2)O}n (4) were synthesized and characterized by X-ray single-crystal, IR spectroscopy, powder diffraction, and elemental analysis. X-ray diffraction analysis revealed that isostructural complexes 1, 2, and 4 displayed 1D structures while complex 3 exhibited 3D coordination polymer with 6(6)-dia topology. In complexes 1, 2, and 4, the adjacent 1D chains were further assembled by pi center dot center dot center dot pi and C=N, pi interactions into the 3D supramolecular framework. Furthermore, optical properties for the compounds were calculated and thermal behaviors of all the complexes were studied in the temperature range of 30 to 1000 degrees C.
