摘要

Gold,palladium and platinum complexes with an unusual isocyanide ligand containing a carboxylic acid function,[AuCl(CNC6H4COOH)],cis-[MI2(CNC6H4COOH)2] and trans-[MI2(CNC6H4COOH)2](M = Pd,Pt)have been isolated. The carboxylic acid group of the coordinated isocyanide acts as a hydrogen donor for hydrogen-bonding and three series of stable hydrogen-bonded liquid crystalline metal complexes have been prepared with decyloxystilbazole. Although all the metal acid derivatives used are not mesomorphic,and decyloxystilbazole only shows an ordered Smectic E phase,four out of the five hydrogen-bonded decyloxystilbazole complexes studied display enantiotropic smectic A or nematic mesophases. The single crystal X-ray diffraction structure of trans-[PdI2(CNC6H4COOH)2]· C4H8O2 has been determined and confirms the formation of a supramolecular array in the solid state supported by hydrogen-bonding.
