Resumen

The diethoxycyclopropenylidene complexes [M(CO)₅{C₃-C₃(OCH₂CH ₃)₂}] (M = Cr, Mo, W)react with K[Fe(CO)₂(Cp)] to give the bimetallic cyclopropenylidene complexes [M(CO)₅{μ₂-C₃(OCH₂CH ₃)}Fe(CO)₂(Cp)], but the second ethoxide is not displaced by excess K[Fe(CO)₂(Cp)]. Spectroscopic evidence (¹H NMR, ¹³C NMR, and IR) as well as a X-ray crystal structure determination of [Cr(CO)₅{μ₂-C₃(OCH₂CH ₃)}Fe(CO)₂ (Cp)] suggests that the central C₃ ring has a great deal of cyclopropenium character.
