abstract: The title compound, C(28)H(52)N(6) (6+)·6Cl(-)·4H(2)O, is a dinucleating 28-membered centrosymmetric hexa-azamacrocyclic complex. The macrocyclic ligand adopts a chair-like conformation, with the crystallographic inversion center located in the macrocyclic cavity. The six chloride ions and four water mol-ecules are situated symmetrically outside the macrocyclic cavity. The crystal structure is stabilized by N-H⋯Cl, N-H⋯O and O-H⋯Cl hydrogen bonds.
