Isocyanide and Phosphine Oxide Coordination in Binuclear Chromium Pacman Complexes.

ABSTRACT: The new binuclear chromium Pacman complex [Cr₂(L)] of the Schiff base pyrrole macrocycle H₄L has been synthesized and structurally characterized. Addition of isocyanide, C≡NR (R = xylyl, ^tBu), or triphenylphosphine oxide donors to [Cr₂(L)] gives contrasting chemistry with the formation of the new coordination compounds [Cr₂(μ-CNR)(L)], in which the isocyanides bridge the two Cr(II) centers, and [Cr₂(OPPh₃)₂(L)], a Cr(II) phosphine oxide adduct with the ligands exogenous to the cleft.
