Iron(II) octaethyltetraazaporphyrin, FeOETAP, a canted ferromagnet with <i>T</i>_c = 5.6 K

Abstract

A four‐coordinate azaporphyrin , FeOETAP (see Figure), is reported that has temperature‐ and field‐dependent properties different from those of other fourcoordinate iron(II) porphyrins and related macrocycles, displaying an apparent canted ferromagnetic state. This behavior is compared to that of M 2⊕ (OETAP), where M = Mn, Co, Ni, Cu, and Zn. magnified image
