The synthesis and characterisation of a series of octahedral dimethyldihalidoplatinum(IV) complexes of 4-alkoxy-4'-stilbazoles with the general formula [PtMe2X2(NC5H4CH=CHC6H4OR)(2)] (X = I or Br, R = n-alkyl) is described. Some of the complexes show mesogenic behaviour. The structure of the complex with X = I and R = C7H15 has been determined by X-ray crystallography, revealing a cis coordination geometry with respect to both the methyl and the substituted 4-alkoxy-4'-stilbazole (n-OST) ligands.

A series of discotic liquid crystals formed by simple hydrogen bonding between phloroglucinol core and alkoxystilbazole peripheral units was prepared. Nematic columnar and hexagonal columnar mesopliases were observed depending on the length of alkyl chains around the aromatic core. (c) 2005 Elsevier Ltd. All rights reserved.
