文摘

Reaction of tris[6-(2-hydroxymethyl)pyridylmethyl]amine, tpa(OH)₃, with V^IVOSO₄¡¤5H₂O resulted in an unexpected redox reaction producing [V^IIILH][V^IIILH₂][PF₆]₃¡¤1.5H₂O (where H₃L is bis(2-hydroxymethylpyridyl)(2-carboxypyridylmethyl)amine). This reaction is interesting in the light of the ability of ascidians to accumulate V^III by reduction of V^V from sea water. It also provides additional proof to the susceptibility of pyridylmethylamines to oxidation by certain metal ions.
