Abstract
The structure of the t-butylacetylene trimer complex [Pd{Cl(Me3CC2H)3}Cl]2(I) has been elucidated from its 1H and 13C n.m.r. spectra as well as by an X-ray structure determination of its triphenylphosphine adduct, [Pd{Cl(Me3CC2H)3}Cl(PPh3)]; complex (I) exists in two η3-allylic forms, an exocyclic and an endocyclic one, which interconvert.Keywords
