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 [NPr₃Me][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.
