Ru complexes containing pyridine dicarboxylate ligands: electronic effects on their catalytic activity toward water oxidation
Two series of mononuclear ruthenium complexes [Ru(pdc)L 3 ] (H 2 pdc = 2,6-pyridinedicarboxylic acid; L = 4-methoxypyridine, 1 ; pyridine, 2 ; pyrazine, 3 ) and [Ru(pdc)L 2 (dmso)] (dmso = dimethyl sulfoxide; L = 4-methoxypyridine, 4 ; pyridine, 5 ) were synthesized and spectroscopically characteriz...

| Summary: | Two series of mononuclear ruthenium complexes [Ru(pdc)L
3
] (H
2
pdc = 2,6-pyridinedicarboxylic acid; L = 4-methoxypyridine,
1
; pyridine,
2
; pyrazine,
3
) and [Ru(pdc)L
2
(dmso)] (dmso = dimethyl sulfoxide; L = 4-methoxypyridine,
4
; pyridine,
5
) were synthesized and spectroscopically characterized. Their catalytic activity toward water oxidation has been examined using Ce
IV
(Ce(NH
4
)
2
(NO
3
)
6
) as the chemical oxidant under acidic conditions. Complexes
1
,
2
and
3
are capable of catalyzing Ce
IV
-driven water oxidation while
4
and
5
are not active. Electronic effects on their catalytic activity were illustrated: electron donating groups increase the catalytic activity. |
