A Caged Neutral 17-Valence-Electron Iron(I) Radical [Fe(CO)₂(Cl)(P((CH₂)₁₀)₃P)]^•: Synthetic, Structural, Spectroscopic, Redox, and Computational Studies.

ABSTRACT: UV irradiation of yellow CH₂Cl₂ solutions of trans-Fe(CO)₃(P((CH₂)₁₀)₃P) (2a) and PMe₃ (10 equiv) gives, in addition to the previously reported dibridgehead diphosphine P((CH₂)₁₀)₃P (46%), a green paramagnetic complex that crystallography shows to be the trigonal-bipyramidal iron(I) radical trans-[Fe(CO)₂(Cl)(P((CH₂)₁₀)₃P)]^• (1a^•; 31% after workup). This is a rare example of an isolable species of the formula [Fe(CO)_4-n(L)_n(X)]^• (n = 0-3, L = two-electron-donor ligand; X = one-electron-donor ligand). Analogous precursors with longer P(C
