[(<i>p</i>-PrⁱC₆H₄Me)₄ Ru₄Mo₄O₁₆]: an amphiphilic organoruthenium oxomolybdenum cluster presenting a unique framework geometry

The amphiphilic title compound, easily accessible from (p- cymene)ruthenium dichloride dimer and sodium molybdate in aqueous solution, presents an unprecedented Ru₄Mo₄O₁₂ framework comprising a central Mo₄O₄ cube with four folded ORuO flaps resembling the sails of a windmill.
