Abstract

The complex {(C5H5)Cr[μ-CH2SiMe2−N(SiMe3)]}2 (1) was obtained by reacting lithium bis(trimethylsilyl)amide (2) with CpCrCl2·THF. A single crystal X-ray diffraction study revealed that the complex is dimeric with two [μ-CH2SiMe2−N(SiMe3)] bridging units and a cis configuration of the two cyclopentadienyl ligands. Bond distances and angles are compared with those observed in [(C5Me5)CrIIMe]2 and [(C5H5)CrIIIMe2]2.
