Synthesis and crystal structure of [Ru3Pt(µ-PPh2)(µ42-C[triple bond, length half m-dash]CBut)(CO)7(dppe)](dppe = Ph2PCH2CH2PPh2), a butterfly cluster containing an unusually bonded alkynyl ligand: a model for an intermediate molecular geometry in a cluster-ligand rearrangement

Abstract

Reaction of [Ru3Pt(µ-H)(µ42-C[triple bond, length half m-dash]CBut)(CO)9(L2)]la(L2= dppe) with Ph2PC[triple bond, length half m-dash]CPPh2 affords the butterfly cluster [Ru3Pt(µ-PPh2)(µ42-C[triple bond, length half m-dash]CBut)(CO)7(dppe)]3; the metal skeleton and µ42 alkynyl coordination mode in 3 represent a likely model for a transition geometry in the interconversion of 1 and its vinylidene tautomer [Ru3Pt{µ42-C[double bond, length half m-dash]C(H)But}(CO)9(L2)]2.
