title: Multimetallic synergic sedation of a labile sodium atrane: synthesis and characterization of a tetranuclear sodium atrane cation complex.
abstract: A series of sodium and aluminum atrane complexes of Na(3)L(THF)(5) (1), [AlLMe][Na(4)L(THF)(6)] (2), AlL(THF) (3), AlNaLMe(THF)(2) (4), and AlNaLOBn(THF)(2) (5), wherein L = tris(2-oxy-4,6-di-tert-butyl-benzyl)amine, were synthesized and characterized by NMR, X-ray crystallography, and elemental analysis. The trinuclear sodium atrane complex of Na(3)L(THF)(5) (1) is labile at room temperature; however, the tetranuclear sodium atrane cation in complex 2 can be stabilized by a multimetallic synergetic effect due to a firm interaction ring of -[Na-O-benzene](3)-. Complex 2 is also the first example of a sodatrane and alumatrane ion-paired complex in which both the cationic and anionic moieties contain an atrane ligand.
