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; 90 degree angle (Fe-O-Fe') = 166.7(3) degrees, and d(Fe.Fe') = 3.556 A. Crystal data for C(70)H(57)ClF(12)Fe(2)N(8)O(3)P (1.PF(6)): triclinic, Ponemacr;, a = 13.185(3) A, b = 14.590 (3) A, c = 16.885(4) A, alpha = 104.219(4) degrees, beta = 91.572(4) degrees
在本文中,我们描述了由卟啉和三脚架氮配体TMPA [TMPA = tris(2-pyridylmethyl)amine]支撑的一系列血红素/非血红素Fe-O-Fe'配合物的合成和研究。[[((6)L)Fe-O-Fe(X)](+)(1)的完整合成(X = OMe(-)或Cl(-),比例为69:31),其中(6)L是5-(oO-[(N,N-双(2-吡啶基甲基)-2-(6-甲氧基)吡啶甲基甲胺)苯基] -10,15,20-三(2,6-二氟苯基)卟啉的二价阴离子, 1.PF(6)的晶体结构揭示了一个分子内血红素/非血红素二铁络合物,由Fe-O-Fe'部分桥接; 90度角(Fe-O-Fe')= 166.7(3)度,d(Fe.Fe')= 3.556 A.C(70)H(57)ClF(12)Fe(2)N(8)O(3)P(1.PF(6))的晶体数据:三斜晶,Ponemacr;,a = 13.185(3)A,b
