Abstract
Molecular addition compounds of tin tetrahalides with triphenylphosphine and triphenylarsine have been prepared. The analytical results show that triphenylphosphine forms both 1:2 ([Formula: see text]) and 1:1 ([Formula: see text]) adducts (L = ligand), whereas triphenylarsine forms only 1:2 adducts. The effect of addition of these ligands on the ν(Sn—X) (where X = Cl, Br) of the Lewis acids has been studied. In all cases, νd(Sn—X) have been found to shift to a lower frequency region on coordination. Tentative assignments for ν(Sn—Y) (where Y = P, As) have been discussed on the basis of the experimental results.Les complexes d'addition moléculaire de tetrahalogénures d'étain et la triphénylarsine et la triphénylphosphine ont été préparés. Les résultats analytiques indiquent que la triphénylphosphine forme deux sortes de complexes[Formula: see text] et[Formula: see text] (L est le ligand), tandis que la triphénylarsine ne forme qu'une sorte de complexes[Formula: see text]. L'effet de l'addition de ces ligands sur la fréquence ν(Sn—X) (où X = Cl ou Br) des acides de Lewis a été étudié. Dans chaque cas, νd(Sn—X) diminue à cause de la coordination. On discute aussi de l'attribution possible de certaines bandes à ν(Sn—Y) (où Y = P ou As).
