Reaction of 4'-(2-propyn-1-oxy)-2,2':6',2''-terpyridine (HC triple bond CCH2Oterpy) with trans-[PtI2(PEt3)2] regioselectively metallates the alkyne to give trans-[Pt(C triple bond CCH2Oterpy)2(PEt3)2] which, when treated with Fe(II), gives a [2 + 2]-metallocycle.

The synthesis and characterization of the ligands R3PAu(1-H) (R =Bu-n, Ph) and (1-H)Au(mu-dppe)Au(1-H) (1 = HC CCH(2)Otpy, tpy = 2,2 ':6 ',2 ''-terpyridme) are reported. The single crystal structures of (Bu3PAu)-Bu-n(1-H) and (1-H)Au(mu-dppe)Au(1-H) have been determined, and weak hydrogen bonding rather than aurophilic interactions operate between the molecules in the solid state.

A series of 2.2':6'.2"-terpyridine (tpy) ligands functionalized in the 4'-position with alkyne substituents has been prepared and characterized. Treatment of these ligands with [RuCl3(tpy)] yields complexes with pendant alkyne groups which then readily react with Co-2(CO)(8) to give novel compounds containing both cluster and classical coordination motifs. The new compounds are characterized by mass spectrometric and spectroscopic methods, and the single crystal structure of [Ru(tpy)(4'-HC=CCH(2)Otpy)][PF6](2) is reported.
