trans-Aquachloro[(1R,4R,8S,11S)-6,13-diammonio-6,13-dimethyl-1,4,8,11-tetra­azacyclo­tetra­decane-κ⁴N^1,4,8,11]nickel(II) trichloride trihydrate

The title compound, [NiCl(C₁₂H₃₂N₆)(H₂O)]Cl₃·3H₂O, has the bis­(diamine)-substituted cyclic tetra­amine in a planar coordination to triplet ground-state Ni^II [average Ni—N = 2.068 (3) Å], with a chloride ion [Ni—Cl = 2.4520 (5) Å] and a water mol­ecule [Ni—O = 2.177 (2) Å] coordinated in the axial sites. The amine substituents are protonated and equatorially oriented. The amine groups, ammonium groups, water molecules and chloride ions are linked by an extensive hydrogen-bonding network.
