Reaction of tris(5-amino-2-ethoxy-3-isopropylphenyl)methane and pyridine-2,6-dicarbonyl-dichloride affords a multi-dentate cryptand in 48% yield. Metallation with iron(III) chloride results in a substantial conformational change of this ligand to give a trianionic triiron(III) complex. Ferric cations line the periphery of the internal cavity with each adopting a square pyramidal N(3)Cl(2) coordination environment.
三（5-氨基-2-乙氧基-3-异丙基苯基）甲烷与吡啶-2,6-二羰酰氯反应生成多齿穴醚，产率为 48%。用三氯化铁进行金属化反应导致该配体发生显著的构象变化，生成三价铁(III)的三核配合物。三价铁离子排列在内部空腔的外围，每个离子采用 square pyramidal N(3)Cl(2)配位环境。
