The ZnII atom in the cation of the title salt, [Zn(C2H3O2)(C18H40N4)]ClO4, is five-coordinated by the four N atoms of the macrocycle and the O atom of the monodentate acetate ligand. The N4O donor set is based on a trigonal bipyramid with two N atoms

The CoIII atom in the title complex, [CoCl2(C40H48N4)]ClO4, is octahedrally coordinated within a trans-Cl2N4 donor set provided by the tetradentate macrocylic ligand and two chloride ions. The N—H atoms, which are orientated to one side of the N4 p

The structure determination of the title salt, C18H42N42+·2ClO4−, reveals that protonation has occurred at diagonally opposite amine N atoms. Intramolecular N—H...N hydrogen bonds stabilize the conformation of the dication. In the crystal, the d

In the crystal structure of the nitrate salt, columns of di-cationic macrocycles, each disposed about a center of inversion, are interspersed by pairs of nitrate anions that form charged-assisted N–H···O hydrogen-bonding interactions, reinforced
