✦ Synopsis


The absorption spectra, emission spectra, emission lifetimes and photochemical and electrochemical behaviour of six monomeric cyclometallated complexes [Pd(CNN)X14+ (where CNN is the C-deprotonated form of 2acetylpyridine-phenylhydrazone and X is I-, Cl-, CMepy, PPh,, P(QPh), P(OMe),) and two dimeric cyclometallated complexes [(CNN)Pd(XX)Pd(NNC)]*' (where XX is 4,4'-bipyridine (4,4'-bpy) or bis(diphenylphosphino)methane (dppm)) were studied. The relatively intense absorption band exhibited by the complexes at 450 nm and the luminescence emission observed at 298 and 77 K were assigned to in&a&and (IL) transitions with remarkable charge transfer character (ILCT).
