The mononuclear cations [(eta5-C5Me5)RhCl(bpym)]+ (1), [(eta5-C5Me5)IrCl(bpym)]+ (2), [(eta6-p-PriC6H4Me)RuCl(bpym)]+ (3) and [(eta6-C6Me6)RuCl(bpym)]+ (4) as well as the dinuclear dications [{(eta5-C5Me5)RhCl}2(bpym)]2+ (5), [{(eta5-C5Me5)IrCl}2(bpym)]2+ (6), [{(eta6-p-PriC6H4Me)RuCl}2(bpym)]2+ (7) and [{(eta6-C6Me6)RuCl}2(bpym)]2+ (8) have been synthesised from 2,2´-bipyrimidine (bpym) and the corresponding chloro complexes [(eta5-C5Me5)RhCl2]2, [(eta5-C5Me5)IrCl2]2, [(eta6-PriC6H4Me)RuCl2]2 and [(eta6-C6Me6)RuCl2]2, respectively. The X-ray crystal structure analyses of [3][PF6], [5][PF6]2, [6][CF3SO3]2 and [7][PF6]2 reveal a typical piano-stool geometry around the metal centres; in the dinuclear complexes the chloro ligands attached to the two metal centres are found to be, with respect to each other, cis oriented for 5 and 6 but trans for 7. The electrochemical behaviour of 1–8 has been studied by voltammetric methods.

Jedno- a dvojjaderné Ir, Rh a Ru komplexy obsahující současně %22měkké%22 chelátující organické a %22tvrdé%22 hydrofilní ligandy představují stavební jednotky pro supramolekulární materiály a současně jsou slibnými hydrogenačními katalyzátory. Elektrochemické studium oxidace serií těchto sloučenin, které obsahují karboxyláto-pyrazinové ligandy umožnilo charakterizovat jejich redox vlastnosti a intramolekulární elektronické interakce a korelovat je s katalytickou aktivitou. Z hlediska supramolekulární chemie bylo zjištěno, že vhodná substituce umožní oxidativní dimerizaci těchto látek.
