Synthesis and magnetic characterization of a dinuclear complex of low-coordinate iron(II).

ABSTRACT: Low-coordinate ions possess exciting magnetic, optical, and reactive properties that may afford novel material physics. Hence, it is important to test both synthetic methods for realizing extended solids of such ions as well as the properties of smaller molecular fragments of envisioned future materials. Herein, we report the synthesis and characterization of a new dinuclear Fe species, [{(Me3Si2)2N}Fe{μ-p-{HN(SiMe3)}(C6Me4){N(SiMe3)}}2Fe{N(SiMe3)2}] (1), formed through a transamination reaction between [Fe{N(SiMe3)2}2]2 and the bulky diamine p-{HN(SiMe3)}2(C6Me4) (L). The Fe centers of this dimer assume a pseudo-trigonal-planar, three-coordinate conformation in 1, bridged by two aromatic diamines. Single-crystal X-ray diffraction, IR spectroscopy, and Mössbauer spectroscopy enable the ass
