Formation of a Tetranuclear High–Spin Iron(II,III,II,III) Mixed Valence Complex

A class II mixed valent Fe4(II,III,II,III) complex [Fe4(Me4-tpdp)2(μ-F)2(OH)2(H2O)2](BF4)4 was synthesized, where HMe4-tpdp is N,N,N′,N′-tetrakis[2-(6-methylpyridyl)methyl]-1,3-diamino-2-propanol. The crystal structure shows that the complex cation consists of two alkoxo-bridged dinuclear units which are connected by two fluoro bridges to form a bilayered structure (a box structure).
