Abstract

Summary: The new compound [C₆H₅Si(OCH₂CH₂)₃N]-Cr(CO)₃ has been prepared and characterized by elemental analysis, IR,¹H NMR, and ¹³C NMR spectroscopy, and X-ray diffraction. [C₆H₅Si(OCH2CH₂)3N]Cr(CO)3 crystallizes in the orthorhombic space group Pbca, with a = 12.078 (2) A, b = 12.347 (1) Â, c = 21.917 (3) Â, and Z — 8. The molecule possesses the usual silatrane skeleton containing a five-coordinated silicon atom. The N-Si distance (2.108 (5) Λ) is somewhat shorter than that in phenylsilatrane. This is the first case where the crystal structure of the silatrane derivative, which acts as a τ-coordinating ligand to transition metals, has been determined. This compound is a versatile starting material for a wide range of complexes, in particular for those of the general formula [C_eH₅Si(OCH₂CH₂)₃N]Cr(CO)₂L (L = PPh₃, P(CH₂CH₂CN)₃, and AsPh₃) and |[C₆H₅SKOCH₂CH₂)₃]Cr-(CO)₂}₂(m-L-L) (L-L = dppe).
