Abstract

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