Abstract
In a second crystal modification 4′ the stannylene [2,3,5-(CF3)3C6H2]2 Sn forms a weakly associated dimer with a long tin–tin distance of 3.639 (1)Å; this structure is compared with the known dimeric structures of the species [(PhCH2)3C5ln]25[(PhCh2)5C5Tl]26 and 2,2′,5,5′-tetramethylbistibole 7 with an s2 electronic configuration.Keywords
