Several new mononuclear and dinuclear Ru(II) complexes incorporating 2,2′:6′,2”-terpyridine and acetylacetonate as ancillary ligands and phenylcyanamide derivative ligands [Ru(tpy)(acac)(L)] and [{Ru(tpy)(acac)}2(μ-L’)] (tpy = 2,2′:6′,2”-terpyridine, acac = acetylacetonate, L = hmbpcyd = 4-(3-hydroxy-3-methylbutynyl)phenylcyanamide anion (2) and epcyd = 4-ethynylphenylcyanamide anion (3) and L’ = bcpda = bis(4-cyanamidophenyl)diacetylene dianion (4) and bcpea = 9,10-bis(4-cyanamidophenylethynyl)anthracene dianion (5)) were synthesized in a stepwise manner starting from [Ru(tpy)(acac)(Ipcyd)] (1), where Ipcyd = 4-iodophenylcyanamide anion. Ph4As+ salts of the phenylcyanamide derivative ligands were also prepared The four complexes were characterized by UV-visible, IR, ES-MS, electrochem. and 1H NMR. Mononuclear complexes 2 and 3 were further characterized by 13C NMR. The single crystal x-ray structure of 2 was determined, it crystallized with one mol. of H2O with empirical formula of C32H31N5O5Ru, in a monoclinic crystal system and space group of P21/n with a 17.642(5), b 9.634(2), c 20.063(7) Å, β 92.65(3)° and Z = 4. The structure was refined to a final R factor of 0.040. The Ru(III/II) couple of 1–3 appeared around 0.34 V vs. the SCE in DMF and at a slightly higher potential, around 0.36-0.37 V for 4 and 5. Spectroelectrochem. studies were also performed for 4 and 5, no intervalence transition was observed despite all attempts.
