A small coordination constitutional dynamic library (CDL) is self-assembled from Cu2+ ions and the ortho bis-(3-acetylacetone) benzene ligand. Two coordination polygons, a rhomboid and a triangle, establish a dynamic equilibrium. Quantitative sorting of the rhomboidal polygon is reversibly obtained by crystallization.

Abstract
A small coordination constitutional dynamic library (CDL) is self-assembled from Cu2+ ions and the ortho bis-(3-acetylacetone) benzene ligand. Two coordination polygons, a rhomboid and a triangle, establish a dynamic equilibrium. Quantitative sorting of the rhomboidal polygon is reversibly obtained by crystallization. Thermodynamic and kinetic aspects ruling the CDL system have been elucidated.File in questo prodotto:
