20.500.12556/DiRROS-28297 Molecular dynamics in tetrafluoridoborate salts of divalent metals studied by nuclear magnetic resonance spectroscopy Fluoridoborate (BF4−) salts are linchpins across synthesis and catalysis, key constituents of ionic liquids, and promising electro-lytes and additives in next-generation multivalent rechargeable batteries. Despite this reach, quantitative links between crystalchemistry and anion motion remain scarce. Here, we present a molecular dynamics study of four such salts, namely M(BF4 ) 2(M = Ca 2+, Sr 2+, Ba 2+, Cd2+), by means of nuclear magnetic resonance spectroscopy (NMR). We measured the temperature depen-dence of static 19 F NMR spectra and spin-lattice relaxation and determined the values of activation energies for the thermally-activated reorientations for the BF4− tetrahedra. We draw a comparison with systems with similar geometries, such as thewell-studied complex metal borohydrides. fluorides metal tetrafluoridoborates molecular dynamics nuclear magnetic resonance spectroscopy fluoridi kovinski fluoridoborati molekulska dinamika spektroskopija jedrske magnetne resonance true false true Wiley Nemčija Angleški jezik Slovenski jezik © 2026 The Author(s).
