Zusammenfassung:The versatile metalloligand [{HC&z.tbd;CC(NDipp) 2 } 2 Au 2 ] (dipp = 2,6-diisopropylphenyl) was converted into early-late heterotetrametallic complexes [{ClCp 2 MC&z.tbd;CC(NDipp) 2 } 2 Au 2 ] (M = Ti, Zr). These compounds show photoluminescence with either remarkably different (Ti) or similar (Zr) features as compared to related solely coinage metal containing acetylide amidinate complexes. Reaction of the ethynyl compound [{HC&z.tbd;CC(NDipp) 2 } 2 Au 2 ] with n -BuLi followed by Cp 2 MCl 2 (M = Ti, Zr) leads to two group IV - gold( i ) heterobimetallic complexes with different photoluminescence properties.
