© 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Reaction of Mo(CO)6 with Bu4NI and I2 in diglyme yielded a new butterfly MoIII cluster [Mo4OI12]2–. The structure of tetraphen-ylphosphonium salt was determined by X-ray single crystal diffraction. Ph4P+ and Bu4N+ salts were further characterized by elemental analy-sis, mass spectrometry, energy-dispersive X-ray (EDX), IR, Raman, and UV/Vis spectroscopy and CVA studies. The cluster anion has a butterfly array of molybdenum atoms and can be represented as [Mo4(μ4-O)(μ3-I)2(μ2-I4)I6]2–.
