摘要： 合成了一种第五配位基为叔胺的尾式卟啉铁(meso—[邻-(4-二乙胺基丁酰胺基)本基]三苯基卟啉合铁(Ⅱ),meso-MDBPTPPFe(Ⅱ))同NO的配合物mesoMDBPTPPFe(Ⅱ)NO。用光谱方法研究了配合物的结构;用分子轨道理论解释了配合物中心离子铁是五配位的原因。

Abstract: Anew tailed iron( Ⅱ )porphyrin complex mcso-MDBPTPPFe( Ⅱ ), with a tailed Et2N-as axial base,reacts with nitric oxide to form adduct meso-MDBPTPPFe( Ⅱ ) NO. The N-Ostretching frequency for this adduct is 1671cm-1. Spectral results demonstrate that when meso-MDBPTPPFe( Ⅱ ) is coordinated by NOin the sixth coordination position the axial coordinated base is away from iron because the unpaired electron of NOhas to go into the antibonding orbital of sp3(N) + dz2(Fe). The observed three g values in meso-MDBPTPPFe( Ⅱ )NO EPRspectrum indicate that the dxz and dyz orbitals are nondegenerate and the iron-nitric oxide unite is bent.
