Coordination assemblies of metallacyclic, prismatic and tubular molecular architectures based on the non-rigid ligands

This microreview covers recent advances in the assembly of coordination molecular architectures showing cyclic, prismatic and tubular structures based on the semi-rigid or flexible ligands. Four assembly routes are outlined depending on the symmetry interactions between specific ligands and metal ions. ((c) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007).
