Abstract
The cobalt atom in the structures studied is situated in the center of an octahedron involving donor atoms N and 3O organic ligands Heida or Bcegly (ions of hydroxyethyliminodiacetate or bis(carbamoylethyl)aminoacetate, respectively), water molecule oxygen atom, and a carboxylic atom of the neighboring ligand in the trans-position to the N atom, so that each (II) ion is linked with two organic anions. This results in a formation of infinite chains - uncharged [Co(Heida)(H2O)](n) or cationic {[Co(Bcegly)(H2O)](+)}(n). In both cases, a molecule of crystallization water is present, and in the second case, the charge of the chains is compensated by perchlorate ions. Aminoacetic cycle of the Heida ligand is approximately coplanar to another such cycle, while a similar cycle of the Bcegly ligand is in the plane of one of six-membered aminopropionamide cycles.
