    Description / Table of Contents: Ammonium Chloro(thio)phosphate Betaines, a Class of Coordination-stabilized Chloro(thio)metaphosphatesAmmonium chloro(thio)phosphate betaines behave like systems being in equilibrium with tert. amine and monomeric chloro(thio)metaphosphate. In solution at room temperature the amine component can be displaced by stronger donors. Mass spectra reveal the presence of ClPS2 as monomer and dimer, of ClPO2 by fragment ions of the dimer, trimer, and tetramer before reorganization takes place to form PXCl3 and P4X10 (X = O, S). Detection of ClPOS fails owing to fast equilibration into ClPO2 and ClPS2.
    Notes: Ammonium-chlor(thio)phosphat-Betaine verhalten sich wie Systeme, die im Gleichgewicht stehen mit tert. Amin und monomerem Chlor(thio)metaphosphat. In Lösung kann die Amin-Komponente bei Raumtemperatur durch stärkere Donoren verdrängt werden. ClPS2 ist im Massenspektrum als Mono- und Dimeres, ClPO2 in Gestalt von Fragmentionen des Di-, Tri- und Tetrameren nachweisbar, bevor Reorganisation zu PXCl3 und P4X10 (X = O, S) eintritt. ClPOS entzieht sich einem Nachweis durch schnelle Symmetrisierung zu ClPO2 und ClPS2.
