Non-classical polyinterhalides of chlorine monofluoride: experimental and theoretical characterization of [F(ClF)3]−. Issue 39 (19th April 2021) - Pröhm, Patrick
Abstract : The [F(ClF)3 ] − anion was synthesized from an organic chloride salt and chlorine monofluoride. Comparison between the [F(ClF)3 ] − anion and other permutated chlorine fluorine heptahalides reveals the unique effect of a central fluoride ion. Abstract : We present the synthesis and characterization of the first non-classical Cl(i ) polyinterhalide [NMe4 ][F(ClF)3 ] as well as the homologous polychloride [NPr3 Me][Cl7 ]. Both salts were obtained from the reaction of the corresponding ammonium chlorides with ClF or Cl2, respectively. Quantum-chemical investigations predict an unexpected planar structure for the [F(ClF)3 ] − anion.
