(Carbonato-κ2O,O′)bis(di-2-pyridylamine-κ2N,N′)cobalt(III) bromide

In the title compound, [Co(CO3)(C10H9N3)2]Br, a distorted octahedral coordination of the CoIII atom is completed by four N atoms of the two chelating di-2-pyridylamine ligands and two O atoms of the chelating carbonate anion. The di-2-pyridylamine ligands are nonplanar and the dihedral angles between the 2-pyridyl groups are 29.11 (9) and 37.15 (12)°. The coordination cation, which has approximate C2 symmetry, is connected to the bromide ion via an N—H...Br hydrogen bond. The ionic pair thus formed is further assembled into a dimer via N—H...O interactions about an inversion centre. A set of weaker C—H...O and C—H...Br interactions connect the dimers into a three-dimensional network.
