cis-Bromido(methyl­amine)­bis­(propane-1,3-di­amine)­cobalt(III) dibromide

In the title compound, [CoBr(CH₅N)(C₃H₁₀N₂)₂]Br₂, the cobalt^III ion has a distorted octa­hedral coordination environment and is surrounded by four N atoms in the equatorial plane, with an additional N atom and the Br atom occupying the axial positions. In the crystal, the complex cation and the two counter anions are linked via N—H...Br and C—H...Br hydrogen bonds, forming a three-dimensional network.

trans-Diamminedichloridobis(1H-imidazole-κN³)nickel(II)

The whole mol­ecule of the title compound, [NiCl₂(C₃H₄N₂)₂(NH₃)₂], is generated by inversion symmetry. The Ni^II ion, which is located on an inversion center, has a distorted octa­hedral coordination environment and is surrounded by two ammine N atoms and two Cl atoms in the equatorial plane, with two N atoms of two imidazole groups occupying the axial positions. The imidazole ring makes a dihedral angle of 81.78 (18)° with the Ni/N/Cl equatorial plane. In the crystal, mol­ecules are linked via N—H...Cl hydrogen bonds and C—H...π inter­actions, forming a three-dimensional network.
