摘要:
Reaction of 2,6-bis(bis(2-pyridylmethyl)amino)methylpyridine (bpa-tpa) with CO(ClO4)(2).6H(2)O has produced [Co(tpaCO(2)) Cl](ClO4), the first structurally characterised cobalt(III) complex of a ligand based on the tris(2-pyridylmethyl)amine (tpa) skeleton; the formation of tpaCO(2)(-) in the reaction highlights the instability of pyridylmethylamines to oxidative cleavage, which has implications for the long-term stability of catalysts prepared from such ligands.
