dc.description.abstract | An anionic hexanuclear NiII metallamacrocycle with endo and exo linking sites has been employed as a building block to generate a series of capsules and bowls of nanometric size. The supramolecular arrangement of the {Ni6} rings was tailored by the size of the alkali cations, showing the transition from {Ni6-M2-Ni6} capsules (M = LiI and NaI) to {Ni6-M} bowls (M = KI and CsI). The alkyl co-cations are determinant to stabilize the assemblies by means of CHꞏꞏꞏ interactions on the exo side of the metallamacrocycles. The effect on the topology of the supramolecular assemblies of the cation size, cation charge, Et3NH+ or Me4N+ countercations has been analysed. Magnetic mesurements reveal the presence of ferromagnetic and antiferromagnetic interactions inside the rings that allow a S = 0 ground state. | - |
