In the title compound, [Mg(C3H3N2)4(H2O)2]Cl2, the MgII cation lies on a crystallographic inversion centre and is coordinated by two water molecules and four N-atom donors from monodentate imidazole ligands, giving a slightly distorted octahedral stereochemistry. In the crystal, water O-HCl and imidazole N-HCl hydrogen bonds give rise to a three-dimensional structure.
