Abstract: | Contributions to the Chemistry of Phosphorus. 143. Li4P26 and Na4P26, the First Salts with Hexacosaphosphid(4?) Ions The hexacosaphosphides Li4P26 ( 1 ) and Na4P26 ( 2 ) are formed besides other polyphosphides in the reaction of white phosphorus with lithium dihydrogenphosphide or sodium. 1 also results from the decomposition of Li2HP7 in tetrahydrofuran at room temperature and can be obtained pure as a crystalline solvent adduct Li4P26 · 16 THF. According to 2D?31P-NMR spectroscopic investigations the P264? ion is a conjucto-phosphane of two P7(5)?-and two P9(3)?-unit groups with structures analogous to norbornane and deltacyclane, respectively. |
