非血红素氧铁（IV）配合物[(N4Py)Fe(IV)(O)](2+) [N4Py = N，N-双（2-吡啶基甲基）-N-双（2-吡啶基）甲胺]的光催化形成有效地通过电子从钌配合物[Ru(II)(bpy)(3)](2+)* （bpy = 2,2'-联吡啶）的激发态转移到[Co(III)(NH(3))(5)Cl](2+)，并以2等量的[Ru(III)(bpy)(3)]（3+）和H(2)O作为氧源逐步电子转移氧化[(N4Py)Fe(II)]（2+）。氧化铁（IV）配合物是由[(N4Py)Fe(II)]（2+）与[Ru(III)(bpy)(3)]（3+）的化学氧化和[(N4Py)Fe(II)]（2+）的电化学氧化独立生成的。
The photocatalytic formation of a non-heme oxoiron (IV) complex, [(N4Py)Fe(IV)(O)](2+) [N4Py = N,N-bis(2-pyridylmethyl)-N-bis(2-pyridyl)methylamine], efficiently proceeds via electron transfer from the excited state of a ruthenium complex, [Ru(II)(bpy)(3)](2+)* (bpy = 2,2'-bipyridine) to [Co(III)(NH(3))(5)Cl](2+) and stepwise electron-transfer oxidation of [(N4Py)Fe(II)](2+) with 2 equiv of [Ru(III)(bpy)(3)](3+) and H(2)O as an oxygen source. The oxoiron(IV) complex was independently generated by both chemical oxidation of [(N4Py)Fe(II)](2+) with [Ru(III)(bpy)(3)](3+) and electrochemical oxidation of [(N4Py)Fe(II)](2+).
