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.
