Kalium-und Tetrachloroantimon(V)-phosphate / Potassium and Tetrachloroantimony(V) Phosphates

Abstract
The potassium dimethoxi-, -dimethylaminomethoxi- and -bis(dimethylamino)phosphates (1), (2) and (3) were prepared by reaction of KOH and the corresponding phos­phoric esterchlorides. 2 reacts with antimony(V) chloride to yield the dimeric tetrachloro- antimony(V) dimethylaminomethoxiphosphate (4). The crystal and molecular structures of 4 and the dimeric tetrachloroantimony(V) dimethoxiphosphate (5) were determined by X-ray analysis. The vibrational and NMR spectra of 1-4 are reported and briefly discussed.
