Abstract
Reactions of tetraethylammonium pentachlorostannate(IV) with a variety of Lewis bases have been investigated. Those with acetonitrile, pyridine, tetrahydrofuran, and salicylaldehyde as base (L) result in the formation of adducts [NEt4][SnCl5·L], while with trimethylamine, 2,2′-bipyridyl (bipy), phosphines, arsines, phosphine oxides, and arsine oxides the products are [NEt4]2[SnCl6] and 1:2 adducts of tin(IV) tetrachloride (a 1 : 1 adduct in the case of bipy). Reactions with quinolin-8-ol (Hquin), pentane-2,4-dione (Hpd), and tropolone (Htrop) result in the elimination of HCl and the formation of [NEt44][SnCl4L′](L′= quin, pd, or trop). Mössbauer quadrupole-splitting data for the adducts [NEt4][SnCl5·L] are in agreement with those predicted from the point-charge model.Keywords
