Three transition-metal complexes with the macrocyclic ligand meso-5,7,7,12,14,14-hexa­methyl-1,4,8,11-tetra­aza­cyclotetra­decane (L): [Cu(ClO4)2(L)], [Zn(NO3)2(L)] and [CuCl(L)(H2O)]Cl

Synopsis: The three title transition-metal complexes display a distorted 4+2 octahedral environment for the cation, with the macrocycle defining the base. The effect of the different axial ligands in the intra- and intermolecular hydrogen bonding is discussed.

Formula: [Cu(ClO4)2(C18H40N4)], [Zn(NO3)2(C18H40N4)] and [CuCl(C18H40N4)(H2O)]Cl
