C 25H21Cl2N5ORu, monoclinic, P121/c1 (no. 14), a = 12.170(2) Å, b = 11.706(2) Å, c = 20.069 (4) Source of material For the novel ligand a-acetyl-a-phenylazo-4-phenylazomethine (L), a solution of 1-chloro-1-(phenylhydrazono)-2-propanone [1] (10.0 g), aniline (7.4 g), and triethylamine (7.2 g) in ethanol (20 mL) was refluxed for 2 h. The solvent was partially removed under reduced pressure. The yellow solid precipitated upon cooling of the solution was washed with water and crystallized from

The synthesis of trans-[Ru(bpy)LCl 2 ] was achieved by the stepwise addition of equimolar amounts of L, RuCl 3 hydrate and 2,2¢-bipyridine (bpy) and then finally an excess of chloride. The neutral air-stable complex is readily soluble in a range of organic solvents and was recrystallized as dark red platelets from slowly evaporating solutions of dichloromethane (m.p. 364 K).
