The complex {(C 5 H 5 )Cr[μ‐CH 2 SiMe 2 −N(SiMe 3 )]} 2 ( 1 ) was obtained by reacting lithium bis(trimethylsilyl)amide ( 2 ) with CpCrCl 2 ·THF. A single crystal X‐ray diffraction study revealed that the complex is dimeric with two [μ‐CH 2 SiMe 2 −N(SiMe 3 )] bridging units and a cis configuration of the two cyclopentadienyl ligands. Bond distances and angles are compared with those observed in [(C 5 Me 5 )Cr II Me] 2 and [(C 5 H 5 )Cr III Me 2 ] 2 .
