Abstract

Mononuclear Pt^II and the first dinuclear Pt^II complexes along with a cyclometalated heterobimetallic Ir^III/Pd^II complex bearing mesoionic carbene donor ligands are presented starting from the same bis-triazolium salt. The mononuclear Pt^II complex possesses a free triazole moiety which is generated from the corresponding triazolium salt through an N-demethylation reaction, whereas the mononuclear Ir^III complex features an unreacted triazolium unit.
