Tris(oxalato)phosphates, method for their preparation and their use

   
   

The invention relates to tris-(oxalato)phosphates of the general formula M[P(C.sub.2 O.sub.4).sub.3 ] wherein M=H, a metal or N(R.sup.1 R.sup.2 R.sup.3 R.sup.4), where R.sup.1, R.sup.2, R.sup.3, R.sup.4, are independently H or an alkyl group comprising 1 to 8 C atoms. The invention also relates to a method for preparing such compounds as well as to their use.
