Abstract The reaction between MHal 4 (M = Ge, Sn; Hal = Cl, Br) and N(CH 2 CH 2 NRLi) 3 (R = Me, SiMe 3 ) yields 1‐haloazametallatranes 1 − 8 , N(CH 2 CH 2 NR) 3 M−Hal ( 1 , M = Ge, Hal = Cl, R = Me; 2 , M = Ge, Hal = Br, R = Me; 3 , M = Ge, Hal = Cl, R = SiMe 3 ; 4 , M = Ge, Hal = Br, R = SiMe 3 ; 5 , M = Sn, Hal = Cl, R = Me; 6 , M = Sn, Hal = Br, R = Me; 7 , M = Sn, Hal = Cl, R = SiMe 3 ; 8 , M = Sn, Hal = Br, R = SiMe 3 ). The composition and structures of the new compounds were established by elemental analyses, 1 H and 13 C NMR spectroscopy and mass spectrometry. Single crystal structures of 1 and 3 were determined by X‐ray diffraction studies: both compounds show transannular Ge−N ax interactions. (© Wiley‐VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
