Both series of complexes were characterised in solution and the solid state. Cyclic voltammetry shows a largely irreversible Ni(II)/Ni(III) oxidation which becomes easier by ca. 70 mV upon ligand deprotonation, with more subtle variations resulting from the changes in aryl ring substituents. Infrared and 1H NMR spectroscopies both provide evidence for ligand deprotonation leading to the chelate ring becoming

Complexes of the type [M(ppy)(big)], (where M = Pt(II) and Pd(II), ppy is 2-phenylpyridine and big is a 1,5-diarylbiguanide) have been prepared and characterised in solution and in the solid state. The big ligand possesses a DAD triple hydrogen bonding array that is designed to facilitate assembly of the complexes with complementary organic components. In DMF solution and in the solid state, the complexes
