	abstract = {{Several binary heptacoordinate-N4O3-ligand LnL complexes of the lanthanides have been prepared and characterized. The heptadentate ligands are the Schiff base condensation products of tris(2-aminoethyl)amine with 3 equiv of either acetylacetone (to form H-3trac) or a hydroxyacetophenone (to form H-3hatren or H-3datren). The complexes hydrolyze easily but most of the Ln(trac) complexes are stable enough to sublime. Crystals of Yb(trac) were isolated by sublimation, and its structure has been solved; it is the first structurally characterized example of a lanthanide heptadentate ligand complex. Crystals of Yb(trac) are monoclinic},
