A Sulfide-Bridged Diiron(II) Complex with a cis-N₂H₄Ligand.

ABSTRACT: A sulfide-bridged diiron(II) complex bearing a cis-N₂H₄ (hydrazine) ligand has been prepared by reaction of LFe^II(μ-S)Fe^IIL (1; L = sterically encumbered βdiketiminate ligand) with 2 molar equivalents of N₂H₄. The metastable diiron(II) hydrazine complex LFe^II(μ-S)(μH N-NH₂)Fe^II (3) is formed, as shown by crystallography, and NMR, vibrational, and electronic absorption spectroscopies. Compound 3 has been crystallographically characterized as its DBU (1,8-diazabicyclo[5.4.0]undec-7$ene) adduct, which exhibits weak N-H···DBU hydrogen bonding. The synthetic process evolves roughly 2 equivalents of NH₃. The cis-N₂H₄
