“…Each tin is in a tetrahedral environment completed by methyl groups giving the SnC 3 N chromophore. There are three examples in which two tin(IV) atoms are 1,4-bridged by 1,3-butadeine [151], 1,3-butadiynyl [152] or butylene [153. In each case the tin(IV) atoms are tetrahedrally coordinated. There are three examples in which two tin(IV) atoms are 1,4-bridged by 1,3-butadeine [151], 1,3-butadiynyl [152] or butylene [153. In each case the tin(IV) atoms are tetrahedrally coordinated.…”

“…Dans la solution-solide, la conformation de la mol6cule monom6re n'est pas affect6e par la pr6sence des mol6cules polym6res; les angles form,s par les plans diac&yl6ne, amide et chloroph6nyle restent identiques ~t ceux observ6s dans le monom6re pur (Brouty et al, 1983). La mol6cule pr6sente toujours, jusqu'fi l'atome d'azote, une bonne plan~it6 [6carts au plan moyen des atomes (chloroph6nyle except6s) <0,2 A], le plan moyen restant fi 25 ° du plan (110) qui contient les chalnes diac&yl6niques venant se polym6riser.…”

“…Les atomes de la cha3ne diac6tyl~nique subissent, entre leurs positions monom6re et polym6re, un d6placement quadratique moyen r.m.s. (1)= 1,10 A] r6alis6 fi partir des donn~es structurales du monom6re pur (Brouty et al, 1983) sur la base des calculs &ablis par Baughman (1974). Ceci vient donc confirmer qu'un compos6 diac&yl~nique peut encore &re notablement polym~ris-able au-delh des limites pr6vues par Baughman (inactivit6 totale pour r.m.s.d.…”
