Abstract

Not just any old iron! The reduction of a bulky guanidinato iron(II) bromide complex yields a three-coordinate iron(I) dimer that possesses the shortest Fe-Fe interaction (2.127 Å) reported to date. Magnetic, Mössbauer, and computational studies show the unprecedented compound to contain two high-spin iron(I) centers with significant multiple-bond character. A related dimer containing a rare example of an unsupported, carbonyl-free MnMn bond is also described.
