Several new cyclic triphosphenium ions and their 2-arsa-analogues have been identified in solution by 31P NMR spectroscopy. The crystal and molecular structures of the cations 1a,b, as their hexachlorostannate (IV) salts have shown that the five membered heterocyclic rings are planar, whereas the cation 9b as its diphosphanedioxide-bis[pentachlorostannate(IV)] salt is nonplanar, like its saturated
已通过 31 P NMR 光谱在溶液中鉴定了几种新的环状三磷鎓离子及其 2-arsa-类似物。阳离子 1a,b 作为其六氯锡酸盐 (IV) 盐的晶体和分子结构表明五元杂环是平面的,而阳离子 9b 作为其二膦二氧化物-双 [五氯锡酸盐 (IV)] 盐是非平面的,如它的饱和磷对应物。© 2001 John Wiley & Sons, Inc. 杂原子化学 12:501–510, 2001
