Crystal structure and magnetic properties of a Cu_4O_4 cubane complex with N-(2-hydroxybenzyl)-propanolamine

摘要

The crystal structure of [Cu(L~1)]_4(1)(H_2L~1 = N-(2-hydroxybenzyl)-propanolamine) contains a Cu_4O_4 cubane core,involving four intramolecular hydrogen bonds.Magnetic studies reveal a good linear correlation between 2J and the bridge angle #phi#;the more antiferromagnetic trend than the literature correlations for the alkoxo-bridged complexes is ascribed to the additional superex-change pathways via the multiple hydrogen bonds.
