| Abstract: | The structures of aquadichlorobis(1H‐imidazole)cobalt(II), CoCl2(Him)2(H2O)2] (Him is 1H‐imidazole, C3H4N2), (I), and aquadichlorobis(1H‐imidazole)nickel(II), NiCl2(Him)2(H2O)2], (II), are isomorphous and consist of monomers with inversion symmetry. The three monodentate ligands (imidazole, chlorine and aqua), together with their symmetry equivalents, define almost perfect octahedra. Hydrogen‐bonding interactions via the imidazole and aqua H atoms lead to a three‐dimensional network. |
