摘要

The title triethanolamine (TEA) complexes isolated include M(TEA)Cl where M = Li (1), Na (2), K (3), Rb (4), Cs (5) and M(TEA)(2)Cl-2 where M = Mg (6), Ca (7), Sr (8), Ba (9). These compounds were characterized by H-1 NMR, C-13 NMR and mass (FAB) spectroscopies, by elemental analysis and where appropriate by Li-7 and Na-23 NMR spectroscopies. In our hands the constitutions of 7 and 8 differ from those reported by others. The molecular structure of 8, determined by X-ray means, reveals strontium ions bound to two tetradentate TEA molecules. Substantial hydrogen bonding to chlorides in the structure is also evident. Four out of the 20 molecules in the unit cell are also coordinated to a water molecule. (C) 1997 Elsevier Science Ltd. [References: 34]
