Gold complexes of 4-isocyanobenzoic acid, [AuX(CNC6H4CO2H)] (X = C
C–C6H4–C9H19, C6F5, C6F4OC6H13, C6F4C6F4Br) and [(μ-4,4′-C6F4C6F4){Au(CNC6H4CO2H)}2], have been isolated. These metallo-acids are luminescent. The single crystal X-ray diffraction study of [Au(C6F5)(CNC6H4CO2H)]∞ confirms a rod-like structure of the molecule, with a linear coordination around the gold atom, which extends into a supramolecular entity supported by hydrogen bond, gold-gold, and fluorophilic (Fortho⋯Fmeta) interactions. The carboxylic acid group of the gold isocyanide complexes acts also as a hydrogen donor towards the hydrogen acceptor decyloxystilbazole, affording some hydrogen-bonded supramolecular liquid crystals.
