      Thumbnail image of graphical abstract

      Complexes of 4,5-diazafluoren-9-one and 9-phenylethynyl-4,5-diazafluoren-9-ol with zinc and platinum halides have been characterised. Protonation of (9-phenylethynyl-4,5-diazafluoren-9-ol)Co2(CO)6 (17)with HBF4 does not yield a cobalt-stabilised carbocation 21, but instead protonation occurs at the nitrogen atom to form 20, which gives rise to an intricate hydrogen-bonding pattern.

    5. Multidentate N Ligand

      Mononuclear and Dinuclear NiII and CuII Complexes with a Pyrrolecarboxamide Ligand: Core Conversions and Unusual Presence of a Dimer and Two Monomers in the Same Unit Cell (pages 3259–3265)
