| Popis: | In the title complex, [Co(CO3)(C12H12N2)2]Br·3H2O, the CoIII cation has a distorted octahedral coordination environment. It is chelated by four N atoms of two different 5,5′-dimethyl-2,2′-bipyridyl (dmbpy) ligands in axial and equatorial positions, and by two O atoms of a carbonate anion completing the equatorial positions. Although the water molecules are disordered and their H atoms were not located, there are typical O...O distances between 2.8 and 3.0 Å, indicating O—H...O hydrogen bonding. The crystal packing is consolidated by C—H...O and C—H...Br hydrogen bonds, as well as π–π stacking interactions between adjacent pyridine rings of the dmbpy ligands, with centroid–centroid distances of 3.694 (3) and 3.7053 (3) Å. |
