摘要：

The reaction of barium metal granules in tetrahydrofuran with 2,6-di-tert-butylphenol, utilizing gaseous ammonia as a catalyst, followed by addition of hexamethylphosphoramide, yields a monomeric barium species. The corresponding reaction of barium metal granules, 2-(dimethylamino)ethanol, and 2,6-di-tert-butylphenol in toluene yields an identical compound. The species has been characterized by IR, H-1 NMR, and C-13 NMR spectroscopy and single-crystal X-ray studies and shown to be the monomeric barium complex Ba(2,6-Bu(t)2C6H3O)2(HOCH2CH2NMe2)4.2C7H8. Eight-coordination of the metal center is achieved through the agency of the four alcohol and four amino groups of the ethanolamine ligands. The bulky aryloxide anions are hydrogen-bonded to the OH groups of ethanolamine ligands. Crystal data at -154-degrees-C: a = 17.168 (2) angstrom, b = 33.364 (5) angstrom, c = 21.606 (3) angstrom, d(calcd) = 1.169 g cm-3, Z = 8, space group Fd2d.
