An integrated experimental and theoretical approach, based on state-of-the-art Multivariate Curve Resolution and DFT based theoretical analyses, is presented as a means to understand the concentration time evolution of all relevant Zn and organic species in the investigated processes, and accurately characterize the solution structures of the key metal coordination complexes. Specifically, we investigate the dissipative translocation of the Zn²⁺ cation from hexaaza-18-crown-6 to two terpyridine moieties and back again to hexaaza-18-crown-6 using 2-cyano-2-phenylpropanoic acid and its <i>paThe journal of physical chemistry lettersFollowing a Silent Metal Ion: A Combined X-ray Absorption and Nuclear Magnetic Resonance Spectroscopic Study of the Zn²⁺ Cation Dissipative Translocation between Two Different Ligands.PMC9234980RG11916B702B43B9PRIN 2017, 2017KKP5ZRFrateloreto FKieffer ILanzalunga ODi Stefano SCapocasa GTavani FD'Angelo PDi Berto Mancini MDel Giudice DfalseFollowing a Silent Metal Ion: A Combined X-ray Absorption and Nuclear Magnetic Resonance Spectroscopic Study of the Zn²⁺ Cation Dissipative Translocation between Two Different Ligands.The dissipative translocation of the Zn²⁺ ion between two prototypical coordination complexes has been investigated by combining X-ray absorption and ¹H NMR spectroscopy.
