Journal of The Chemical Society, Chemical Communications | 1993

Synthesis and X-ray crystal structure of a stannaimine

Günter Ossig; Anton Meller; Stefanie Freitag; Regine Herbst-Irmer

A stannaimine has been isolated for the first time; the tin atom is surrounded by three nitrogen atoms in a planar arrangement and the tin–nitrogen double bond is shortened by 10 pm compared with tin–nitrogen single bonds.


Journal of The Chemical Society, Chemical Communications | 1991

Synthesis and X-ray crystal structure of germaimines

Anton Meller; Günter Ossig; Walter Maringgele; Dietmar Stalke; Regine Herbst-Irmer; Stefanie Freitag; George M. Sheldrick

Three new germaimines have been synthesized and two of them characterized by X-ray diffraction; the GeN bond lengths agree well with an ab initio prediction for H2GeNH.
