Synthesis, structures and photophysics of novel luminescent platinum-copper complexes

The novel hexanuclear platinum-copper complex [Pt2Cu4(C6F5)4 (C≡CtBu)4] (acetone)2] (1) and the polynuclear derivative [PtCu2(C6F5)2 (C≡CPh)2]x (2), which crystallises in acetone as [Pt2Cu4 (C6F5)4 (C≡CPh)4(acetone)4] (2).(acetone)4, have been prepared using [cis-Pt(C6F5)2(THF)2] and the correspondi...
