The multifunctional ligand bis(diphenylphosphino)-1,9-nonadiyne (1; abbreviated as dpndy) has been prepared by sequential treatment of HC≡C(CH2)5C≡CH with BuLi and PPh 2Cl. Compound 1 reacts with W(CO)4(NCMe)2 to give W(CO)4(η2-dpndy) (2), while the reaction of 1 and W(CO)3(Me3tach) (Me3tach = 1,3,5-trimethyl-1,3,5-triazacyclohexane) produces W(CO)3(η 2-dpndy)(η1-dpndy) (3), [W(CO)3-(η 2-dpndy)]2(μ,η2-dpndy) (4), and the paddle-wheel complex [W(CO)3]2(μ,η 2-dpndy)3 (5). Further treatment of W(CO) 3(Me3tach) with 3 generates the tripodal compound W(CO)3[(μ,η2-dpndy)W(CO)3(η 2-dpndy)]3 (6). The molecular structures of 2 and 5 have been determined by an X-ray diffraction study.
