Sažetak
Copper(II) complexes of 3-methylpicolinic acid (3-MepicH), namely [Cu(3-Mepic)2].2H2O (1) and [Cu(3-Mepic)2(4-pic)] (2) were prepared and characterized by IR spectroscopy and thermal analysis (TGA/DTA). Molecular and crystal structure for 2 was determined by X-ray crystal structure analysis. 1 was prepared by reaction of copper(II) sulfate pentahydrate and 3-methylpicolinic acid in aqueous solution, while 2 was prepared by recrystallization of 1 from 4-picoline solution. Structure analysis revealed square-pyramidal copper(II) coordination and N, O-chelating mode of 3-methylpicolinic acid in 2. Copper(II) ion is coordinated by two 3-Mepic ligands in the basal plane of square pyramid and by 4-picoline molecule in the apical position. A crystal packing of 2 is dominated by weak intermolecular C-H...O hydrogen bonds and pi-pi stacking interactions which form a complex three-dimensional supramolecular architecture.
