摘要：

Structural features of molecular assemblies determine their magnetic properties. This has been expressed in several qualitative and quantitative magnetostructural correlations. Herein two classes of ligands and there structural and magnetic properties will be discussed. 2-Aminoglucose ligands are 2-aminoalcohols derived from a sugar backbone and therefore provide specific structural and chemical properties which can be used as structural directives. Hence, this allows to control the magnetic properties of related polynuclear complexes. On the other hand, triaminoguanidine derivatives as tritopic ligands preset an equilateral triangular arrangement of metal ions with preferentially anti ferromagnetic interactions. This can be utilized to generate higher nuclearity complexes and coordination polymers. (C) 2009 Elsevier B.V. All rights reserved.
