SYNTHESES AND STRUCTURES OF SIX COMPOUNDS THAT CONTAIN THE SODIUM ANION

Abstract

Abstract Crystal structures have been obtained for the sodide (IUPAC, natride) salts, K+(12–crown–4)2–Na− (I), Na+(cryptand[2.2.1])Na−(II), Rb+(18–crown–6)Na−·CH3NH2 (III), K+(18–crown–6) Na−·2(CH3NH2)·3(18–crown–6)(IV), Cs+(cryptand[3.2.2])Na−(V), and (Li+)2(TMPAND)2–(Na−)2·(CH3NH2)(VI), in which TMPAND is 5,12,17–trimethyl–1,5,9,12,17–pentaazabicyclo [7.5.5] nonadecane). The synthesis, handling and crystal growth techniques are described and the properties and structures are compared with those of other alkalides.
