本文报道了一系列以卟啉和三脚架氮配体TMPA [TMPA =三（2-吡啶甲基）胺]为载体的血红素/非血红素Fe-O-Fe'配合物的合成和研究。报道了5-（邻-O-[（N，N-二（2-吡啶甲基）-2-（6-甲氧基）吡啶甲胺）苯基]-10，15，20-三（2，6-二氟苯基）卟啉的阴离子[（L-6）Fe-O-Fe（X）]（+）（1）（X = OMe-或Cl-，69：31）的全合成。测定了1（.）PF（6）是由Fe-O-Fe'桥联的血红素/非血红素双铁络合物;
In this paper, we describe the synthesis and study of a series of heme/non-heme Fe-O-Fe' complexes supported by a porphyrin and the tripodal nitrogen ligand TMPA [TMPA = tris(2-pyridylmethyl)amine]. The complete synthesis of [(L-6)Fe-O-Fe(X)](+) (1) (X = OMe- or Cl-, 69:31 ratio), where L-6 is the dianion of 5-(o-O-[(NN-bis(2-pyridylmethyl)-2-(6-methoxyl)pyridinemethanamine)phenyl]-10,15,20-tris(2,6-difluorophenyl)porphine, is reported. The crystal structure for 1(.)PF(6) reveals an intramolecular heme/non-heme diferric complex bridged by an Fe-O-Fe' moiety;
