Abstract

Abstract The species [{Sn (C 2 H 2 i Pr 3-2, 4, 6) 2} 3] has been obtained in a simple, essentially quantitative, synthesis from SnCl 2 and ArLi in diethyl ether at low temperature. The crystal structure analysis confirms the trimeric nature of the molecular units but reveals some unusual features. The crystal contains the unusual feature of an asymmetric unit that consists of three units of [{SnAr 2} 3] in P2 1/c; the molecular unit is a scalene triangle, ...
