Аннотация:Single crystal structures of N(CH2CH2NSiMe3)(3)Si-Vinyl (1) and N(CH2CH2NSiMe3)(3)Si-n-Butyl (2) were determined by X-ray diffraction studies: both compounds show weak transannular N-ax --> M interactions (1, d(N-ax --> Si) = 2.712(1) Angstrom, 2, d(N-ax --> Ge) = 2.743(3) Angstrom). General trends for molecular structures of the group 14 elements (Si, Ge, Sn) azametallatranes are discussed with also included DFT calculations data. (C) 2004 Elsevier B.V. All rights reserved.
