| Abstract: | A new tetranuclear complex [Fe4 L 2(μ‐O)2(μ‐>OH)2](ClO4)4·H2O ( 1 ), (H L = N,N,N′,N′‐tetrakis‐[(2‐pyridyl)methyl]‐2‐hydroxypropane‐1,3‐diamine) has been synthesized and its crystal structure and magnetic properties are shown. X‐ray crystallography reveals that complex 1 contains a quadruply‐charged, tetranuclear iron(III) cation and four perchlorate anions. In 1 , the Fe4O6 core is composed of a tetrahedron of iron atoms bridged by six oxygen atoms (two oxo, two hydroxo, and two alkoxo groups from L ). This results in an adamantane‐type geometry with the iron atoms occupying the bridgehead positions. Susceptibility data of 1 indicate strong intramolecular antiferromagnetic coupling of high‐spin FeIII atoms. |
