Abstract

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)2Cl2 where M = Mg (6), Ca (7), Sr (8), Ba (9). These compounds were characterized by 1H NMR, 13C NMR and mass (FAB) spectroscopies, by elemental analysis and where appropriate by 7Li and 23Na 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.
