High level ab initio calculations indicate that the anion- anion complex is thermodynamically unstable but kinetically stable with respect to the isolated anions17 p.application/pdfeng(c) Prohens López, Rafael et al., 2017Estructura cristal·lina (Sòlids)AnionsLayer structure (Solids)Anionsinfo:eu-repo/semantics/article6768572020-05-31info:eu-repo/semantics/openAccess
