Bromido(1,4,7,10,13-penta­aza­cyclo­hexa­deca­ne)cobalt(III) dibromide dihydrate

The title salt, [CoBr(C₁₁H₂₇N₅)]Br₂·2H₂O, contains a complex cation with mirror symmetry and two Br⁻ counter-anions that are likewise located on the mirror plane. The central Co^III atom of the complex cation has one Br⁻ ion in an axial position, one N atom of the penta­dentate macrocyclic ligand in the other axial position and four N atoms of the ligand in equatorial positions, defining a distorted octa­hedral coordination geometry. The macrocyclic ligand is coordinated to the Co^III atom within a 5, 6, 5 arrangement of chelate rings in the equatorial plane of the four N atoms. Due to symmetry, the configuration of the chiral N atoms is 1RS, 4SR, 10RS, 13SR. In the crystal, N—H...Br, O—H...Br and N—H...O hydrogen bonds between the complex cation, anions and lattice water mol­ecules generate a three-dimensional network.
