Description
| - Reakce {(.mu.-bpym)[RuCl(terpy)]2}(PF6)2, bpym= 2,2´-bipyrimidine a terpy = 2,2´:6´,2´´-terpyridin, s NaNO2 poskytuje{(.mu.-bpym)[Ru(NO2)(terpy)]2}(PF6)2. Oba dvojjaderné komplexy mohou podstoupit dva reversibilní bpym-centralizované jednoelektronové redukční procesy a dva jednoelektronové oxidační kroky centralizované na kovu, přičemž oxidace probíhá přes meziprodukt se smíšenou valencí a slabým intermetalickým propojením. Okyselení {(.mu.-bpym)[Ru(NO2)(terpy)]2}(PF6)2 nevede k očekávanému {(.mu.-bpym)[Ru(NO)(terpy)]2}6+ ale, pravděpodobně kvůli vysokému náboji, k nerozpusnému, ale strukturálně a IR-spektroskopicky charakterizovanému pseudo-basickému produktu syn-{(.mu.-bpym-(4-OH))[Ru(NO)(terpy)]2}(PF6)5. Přidání jednoho hydroxidu k jedné ze 4-pozic bis-chelátového bpym přeruší aromatickou .pi. konjugaci a je doprovázeno odpovídající změnou intra-pyrimidinových vazebných délek. (cs)
- Reaction of {(.mu.-bpym)[RuCl(terpy)]2}(PF6)2, bpym= 2,2´-bipyrimidine and terpy = 2,2´:6´,2´´-terpyridine, with NaNO2 yields{(.mu.-bpym)[Ru(NO2)(terpy)]2}(PF6)2. Both dinuclear complexes can undergo two reversible bpym-centered one-electron reduction processes and two metal-centered one-electron oxidation steps, the latter involving mixed-valent intermediates with weak intermetallic coupling. Acidification of {(.mu.-bpym)[Ru(NO2)(terpy)]2}(PF6)2 does not lead to the expected {(.mu.-bpym)[Ru(NO)(terpy)]2}6+ but, probably because of the high charge, to the insoluble but structurally and IR-spectroscopically characterised pseudo-base product syn-{(.mu.-bpym-(4-OH))[Ru(NO)(terpy)]2}(PF6)5. The addition of one hydroxide to one of the 4-positions of bis-chelating bpym interrupts the aromatic .pi. conjugation and is accompanied by corresponding intra-pyrimidine bond length variations.
