Polymeric and monomeric copper(II) thiophene- and furancarboxylato complexes. Bridging and terminal coordination of 3-pyridylmethanol

Popis výsledku v původním jazyce

The synthesis and characterization of eight new coordination compounds [Cu(2-tpc)(2)(mu-3-pyme)(2)](n), (1), [Cu(3-Me-2-tpc)(2)(mu-3-pyme)(2)](n) (2), [Cu(5-Me-2-tpc)(2)(mu-3-pyme)(2)](n) (3), [Cu(5-Cl-2-tpc)(2)(3-pyme)(2)] (4), [Cu(2-fuc)(2)(mu-3-pyme)(2)](n), (5), [cu(3-fuc)(2)(mu-3-pyme)(2)](n) (6), [Cu(2,5-Me-2-3-fuc)(2)(mu-3-pyme)(2)](n) (7), and [Cu(5-NO2-2-fuc)(2)(mu-3-pyme)(2)](n) (8) (where 2-tpc is 2-thiophenecarboxylato, 3-Me-2-tpc is 3-methyl-2-thiophenecarboxylato, 5-Me-2-tpc is 5-methyl-2-thiophenecarboxylato, 5-CI-2-tpc is 5-chloro2-thiophenecarboxylato, 2-fuc is 2-furancarboxylato, 3-fuc is 3-furancarboxylato, 2,5-Me-2-3-fuc is 2,5-dimethyl-3-furancarboxylato, 5-NO2-2-fuc is 5-nitro-2-furancarboxylato and 3-pyme is 3-pyridylmethanol) is reported and their X-ray structures were determined. X-ray analysis revealed that samples 1-3 and 5-8 are coordination polymers, whereas the complex 4 is monomeric. The polymeric extension is achieved through bridging N,O-3-pyridylmethanol molecules, resulting in the observation of 2-D (1-3, 5-7) or 1-D polymeric chains (8). In addition, the coordination polymers are also stabilized by strong intramolecular hydrogen bonds. On the other hand, the monomeric compound 4 with monodentate N-coordinated 3-pyridylmethanol ligands forms 1-D supramolecular chain due to strong intermolecular hydrogen bonds. Electronic, IR, EPR spectra and magnetic susceptibility measurements over the temperature range 1.8-300 K are discussed in terms of known crystal and molecular structure. Based on the IR spectra it can be concluded that the type of coordination of 3-pyridyhnethanol as well as hydrogen bonds strongly influence the position and the shape of the stretch vibrations bands assigned to hydroxyl group.
