Reinvestigation of the claim that bis-(η5-cyclopentadienyl)tin(II) and (η5-cyclo-pentadienyl)tricarbonyltungsten hydride form bis-[(η5-cyclopentadienyl)tricarbonyltungsten]tin(II)

Bis-(η5-cyclopentadienyl)tin(II) and (η5-cyclopentadienyl)tricarbonyltungsten hydride form tris-[(η5-cyclopentadienyl)tricarbonyltungsten]tin(IV) hydride which is readily halogenated by halogenated hydro-carbon solvents to form the corresponding tin(IV) halides rather than the bis-[(η5-cyclopentadienyl)tricarbonyl-tungsten]tin(II) product previously claimed.
