Аннотация:Two compounds of a novel-type azagermatrane, N(CH(2)CH(2)NC(6)F(5))(3)Ge-Hal: Hal=Cl (1) Br (2), were prepared via a metathetical reaction of trilithium salt of tetramine, N[CH(2)CH(2)N(Li)C(6)F(5)](3), with corresponding GeHal(4). A single crystal structure of I was determined by the X-ray diffraction study: The compound shows the strongest transannular N(ax)-> Ge interaction (2.148(7) angstrom) among other studied azagermatranes.
