    Abstract

    The synthesis of three new tetranuclear heterometallic CoIII???DyIII planar butterfly coordination complexes is reported of molecular formulae [DyIII2CoIII2(OH)2(teaH)2(acac)6]??MeCN (3), [DyIII2CoIII2(OH)2(bdea)2(acac)6]??2H2O (4) and [DyIII2CoIII2(OH)2(edea)2(acac)6]??2H2O??4MeCN (5) (teaH3 = triethanolamine, bdeaH2 = N-n-butyldiethanolamine, edeaH2 = N-ethyldiethanolamine and acacH = acetylacetone) each of which display single-molecule magnet (SMM) behaviour. Importantly these new compounds are related to several \{CoIII2DyIII2\} SMM compounds allowing for the study of the effect that the subtle changes in structure have on the SMM properties. Ab initio calculations are performed on 3???5, as well as on the related structural derivatives in order to gain insight on the effect the structural changes have on the dynamic magnetic behaviour.
