The alkyne functionalised bidentate N-donor ligand (2-propargyloxyphenyl) bis(pyrazolyl)methane (L) was prepared in high yield from the reaction of (2-hydroxyphenyl)bis(pyrazolyl)methane with propargyl bromide in the presence of base. A series of transition-metal complexes including [MCl2L] (M = Cu, Co, Ni, Zn, Pt), [ML2](NO3)2 (M = Cu, Co, Ni, Zn), [AgL]NO3 and [Pd(L)(dppe)](OTf)2 were prepared and characterised by spectroscopic techniques. In addition, ligand L as well as the Co(ii) and Zn(ii) complexes [CoCl2L]2, [ZnCl 2L] were structurally characterized by single-crystal X-ray diffraction. The organometallic gold(i) and platinum(ii) acetylide complexes [Pz2CH(C6H4-2-OCH2CCAuPPh 3)] and trans-[{Pz2CHC6H4-2-OCH 2CC}2Pt(PPh3)2] were prepared from L and [AuCl(PPh3)] and trans-[PtCl2(PPh3) 2], respectively. Treatment of these complexes with [Pd(OTf) 2(dppe)] or [Cu(MeCN)4]PF6 results in formation of the cationic, mixed-metal complexes, which were isolated (Pt/Pd, Au/Pt) or detected by electrospray mass spectrometry (Au/Cu, Pt/Cu).
