Their synthesis can be done in basic ionic liquids, which form on the addition of a mineral acid, which also delivers the counter anion for the final cluster compound, to an excess of the 1<jats:italic>H<\/jats:italic>\u2010imidazole. Some addition of an auxiliary solvent, like methanol, improves the speed of crystallisation. The cluster unit comprises a hexanuclear Nb<jats:sub>6<\/jats:sub> unit of octahedral shape with the edges bridged by Cl atoms and the exo sites being occupied by N\u2010bonded 1<jats:italic>H<\/jats:italic>\u2010imidazole ligands.
