Title: Topological aspects of lanthanide–adipate–aqua compounds: Close packed and open framework structures

Abstract

A search in the Cambridge Structural Database (CSD) for lanthanide complexes with adipate [OOC(CH{sub 2}){sub 4}COO]{sup 2−} and aqua ligands retrieved a fair number of compounds. To this dataset a new lanthanum metal–organic framework, ([La{sub 2}(adip){sub 3}(H{sub 2}O){sub 2}] (1) (adipH{sub 2}=adipic acid), synthesised and structurally characterized in these labs, was included. The crystal structures of these coordination polymers, of general formulation [Ln{sub 2}(adip){sub 3}(H{sub 2}O){sub x}], exhibit a variety of topologies and dimensionality, which were clustered in different classes and described in detail. It was explored that the majority of these evidences the presence of metal chains or dinuclear Ln{sub 2} entities (separated in both cases by 4.0–4.8 Å), where lanthanide ions are differently connected by carboxylate groups with chelating or oxygen-bridging mode. The different amount of coordinated water molecules appear to affect the solid state networks. Moreover the crystal packing of these compounds shows peculiar aspects and examples were reported in the literature where the long alkyl chain of adipate connectors give rise to interpenetrated structures, or to porous material where lattice water or neutral larger molecules are clathrated. - Graphical abstract: A survey of structures and topologies of lanthanide adipate compounds is presented. A newly synthesized lanthaniummore » adipate complex ([La{sub 2}(adip){sub 3}(H{sub 2}O){sub 2}] (adipH{sub 2}=adipic acid) is also reported. - Highlights: • The use of lanthanide and adipic acid demonstrate the possibility to construct coordination polymer of different dimensionality. • The number of coordination and adipate conformation influence the different topologies. • The ionic radii of the rare earth cations seem also to affect the architecture observed.« less
