New silicon , germanium , and tin containing imido alkyl molybdenum complexes (ArN) 2 Mo(CH 2 EMe 3 ) 2 (Ar is 2,6 diisopropylphenyl; E = Si (1), Ge (2), Sn (3)) were prepared in the crystalline state in 58-66% yields by the reactions of the (ArN) 2 MoCl 2 (DME) com plex with alkyllithium derivatives Me 3 ECH 2 Li (E = Si or Ge) or the Grignard reagents Me 3 ECH 2 MgCl (E = Ge or Sn). The structures of complexes 1-3 and the known analog (ArN) 2 Mo(CH 2 Bu t ) 2 (4) were established by X ray diffraction analysis. Complexes 1-3 were found to be isostructural. The coordination environment about the Mo atom can be described as a distorted tetrahedron. Complex 4 has a similar structure. The Mo-C distance tends to decrease with increasing electron donating ability of the EMe 3 group.
