Abstract

Abstract Ligand 3 has been shown to self-assemble under coordination of copper (II) cations in a 1: 1 ratio in acetonitrile to give equilibrating mixtures of a [2× 2] grid-type tetranuclear structure 1 and a hexanuclear achitecture of hexagonal shape 2. The latter was confirmed by determination of the crystal structure which further indicated that 2 contained acetonitrile molecules and hydroxo groups bound to the copper (II) centers, which are therefore five- ...
