The whole molecule of the title compound, [NiCl2(C3H4N2)2(NH3)2], is generated by inversion symmetry. The NiII 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—HCl hydrogen bonds and C—Hπ interactions, forming a three-dimensional network.

In the title compound, [Ni(C7H12N2)4(H2O)2]Cl2, the nickel(II) ion has a distorted octahedral coordination environment. It is surrounded by three N atoms and one O atom occupying the equatorial plane, and one N and one O atom in the axial positions. The imidazole ring systems are inclined to one another with dihedral angles varying between 38.3 (4) and 74.1 (4)°. In the crystal, molecules are linked via O—HCl hydrogen bonds involving one Cl− anion and the water molecule in the equatorial plane, forming an inversion dimer-like arrangement. The water molecule in the axial position is hydrogen-bonded to both Cl− anions. There are also a number of C—HCl hydrogen bonds present, forming a three-dimensional structure. All four alkyl chains are disordered over two positions with refined occupancy ratios of 0.395 (15):0.605 (15), 0.658 (14):0.342 (14), 0.332 (11):0.668 (11) and 0.622 (12):0.378 (12).

The title molecule, [CoCl2(C5H5N)2(H2O)2], has -1 symmetry with the CoII ion situated on an inversion centre. The cation has a distorted octahedral coordination environment and is surrounded by two N and two Cl atoms in the equatorial plane, while the coordinating water O atoms occupy the axial positions. The crystal exhibits nonmerohedral twinning with two domain states, the volume fractions of which were refined to 0.883 (2) and 0.117 (3). The crystal packing is stabilized by O—HCl hydrogen-bond interactions, forming two-dimensional networks lying parallel to (001). The crystal packing also features π–π interactions between the pyridine rings, with centroid–centroid separations of 3.493 (3) and 3.545 (3) Å.
