Abstract
Crystals of the title compound, (C16H36N)4[(p-NC-C6H4As)4Mo12O46] or (C16H36N)4[{As(C7H4N)}4Mo12O46], were synthesized by the reaction of p-cyanophenylarsonic acid and sodium molybdate at low pH. With nitrile groups pointed into tetrahedral directions, these new organically modified polyoxometallate clusters are potential building blocks in coordination networks.
