Abstract

The low-dimensional Mo6 and Re6 cluster chalcohalides synthesised from solid-state reactions at high temperature are reviewed. Their crystal structures are described in terms of interunit connectivities involving inner and apical ligands shared between adjacent cluster units. It will be shown that such architectures are controlled by the geometry of the M6L14 cluster units, the steric hindrance of the ligands linked to the M6 cluster, the specific location imposed on the halogen or chalcogen ligand and the most favourable electron count on the cluster core, considering halogen and chalcogen stoichiometries.
