Several homoleptic silyl complexes of arsenic(III) and antimony(III), namely As(SiR2R')(3) (R = Me, R' = cyclohexyl (Cy); R = Me, R' = Ph; R = R' = Ph) and Sb(SiPh3)(3), have been prepared via salt elimination reactions of R2R'SiCl and Na3E (E = As or Sb). The structures of two complexes, As(SiMe2Cy)(3) and Sb(SiPh3)(3), have been determined by X-ray crystallography. Both structures possess a three-coordinate Group 15 element centre with a pyramidal geometry of the ESi3 core. (C) 2000 Elsevier Science Ltd. All rights reserved.
