Sažetak
Quinaldic acid (quinolin-2-carboxilic acid), a tryptophane , etabolite, is a well known chelating ligand. Preparation and crystal structures of many transition metal complexes of quinaldic acid have been reported until now. In continuation of our previous research on mercury(II) complexes with quinaldic acid, we have prepared and characterized two cadmium(II) complexes with quinaldic acid, namely diaquabis(quinoline-2-carboxylato)cadmium(II) (1) and trans-bis(dimethylsulfoxide)bis(quinoline-2-carboxylato-N, O)cadmium(II) (2). Complex(1) was prepared by reaction of cadmium(II) acetate and quinaldic acid in the mixture of ethanole and water, while 2 was prepared by recrystallization of 1 in dimethylsulfoxide. Both complexes were characterized by IR spectroscopy and thermal methods (TGA/DTA) and the molecular and crystal structure of 2 was determined by single crystal X-ray analysis. DFT calculations were performed on selected geometries 1 and 2 in order to complement experimental data similar to our previous work.
