Diiron Dithiolate Hydrides Complemented with Proton-Responsive Phosphine-Amine Ligands.

ABSTRACT: The reaction of Fe₂(pdt)(CO)₆ with two equivalents of Ph₂PC₆H₄NH₂ (PNH₂) affords the amido hydride HFe₂(pdt)(CO)₂(PNH₂)(PNH) {[H1H]⁰, pdt^2- = CH₂(CH₂S^-)₂}. Isolated intermediates in this conversion include Fe₂(pdt)(CO)₅-(κ¹-PNH₂) and Fe₂(pdt)(CO)₄(κ²-PNH₂). X-ray crystallographic analysis of [H1H]⁰ shows that the chelating amino/amido-phosphine ligands occupy trans-dibasal positions. The ³¹P NMR spectrum indicates that [H1H]⁰ undergoes rapid proton exchange between the a
