| Abstract: | Derivatives of o-Phenylenephosphate. XV. Synthesis of Tris-(o-phenylenedioxy)-phosphorate(V) The structure of an orthophosphate which had been supposed earlier to represent type 1 , has been proven to be a compound having only one P-nucleus in the molecule, with a penta( 4 ) resp. hexacoordinated ( 5 ) structure depending on the solvent. The triethyl-ammonium salt 8 of this first example of a hexacoordinated phosphoric acid with 6 P O-bonds ( 5 ) is formed simply from tri- als well as from tetra- and pentacoordinated derivatives of phosphorous resp. phosphoric or thiophosphoric acid. |
