Název v původním jazyce

The structures of cobalt(II) and copper(II) complexes derived from 6-(4,5-dihydro-1H-imidazol-5-on-2-yl)pyridine-2-carboxylic acid

Popis výsledku v původním jazyce

6-(4-lsopropy1-1,4-dimethyl-4,5-dihydro-1H-imidazol-5-on-2-y1)pyridine-2-carboxylic acid (1) was used for the preparation of three copper(II) complexes, 5-7, and one cobalt(II) complex, 8. The structures of these complexes were studied in the solid phaseand in solution by means of X-ray diffraction and mass spectrometry. It was found that all the copper(II) complexes exhibit structures in which the copper atom assumes a distorted tetragonal pyramidal configuration. In solution, the neutral complexes Sand 6 were present as an equilibrium mixture of mononuclear and binuclear forms. In the solid phase, the structures of the complexes differ: complex 5 is monomeric, 6 is polymeric and 7 is a cyclic tetramer. In contrast to that, the cobalt complex 8 was found to be trinuclear, with one cobalt(II) ion being bound covalently with the carboxylic groups of two ligands and assuming an octahedral geometry, while the remaining cobalt atoms are bound coordinatively and their geometries correspond
