<i>cis</i>–<i>trans</i>isomerizations and rearrangements during hydrothermal synthesis of metal carboxylates

Abstract

9 1 frameworks has grown drastically over the past few years. The use of multifunctional ligands, such as organometallic complexes, permits the introduction of other functionalities within the frameworks. We have synthesized and characterized a series of metal-organometallic framework (MOMF) materials, derived from simple [CpFe-( 6 -arenecarboxylate)] bridging ligands. Depending on the reaction conditions, solid state structures ranging from simple 1D polymer chains to three dimensional square grid structures have been obtained. For example, the reaction of Ni(NO3)26H2O with [CpFe] + -metalated 1,4-benzenedicarboxylic acid (1) results in [Ni3(1-H)4(H2O)2(-H2O)2][NO3]2, a 3D framework material constructed of square grid nickel-carboxylate networks that are interconnected in the third dimension through additional nickel ions. The synthesis, structure and characterization of these materials will be presented.
