摘要：

Mild thermolysis of (2-pyridyl)(SiMe3)(2)CSbCl2 and [2-(6-Me)pyridyl](SiMe3)NAsCl2 affords, respectively, the chloro-bridged polymeric geminal C-centred distibine(III) complex [(2-pyridyl)(SiMe3)CSbCl](infinity) 1 and the geminal N-centred arsenic(III) amide [(2-(6-Me)pyridyl}NAsCl](2) 2; the proposed mechanism involves the elimination of Me3SiCl and a [2 + 2] stereospecific cis-cycloaddition of the stibaalkene (Sb=C) and arsaimine (As=N) intermediates.
