✦ Synopsis

Single crystal structures of N(CH 2 CH 2 NSiMe 3 ) 3 Si-Vinyl (1) and N(CH 2 CH 2 NSiMe 3 ) 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) ¼ 2.712(1) A ˚, 2, d(N ax ! Ge) ¼ 2.743(3) A ˚). General trends for molecular structures of the group 14 elements (Si, Ge, Sn) azametallatranes are discussed with also included DFT calculations data.
