Synthesis and complexation of N,N-Bis(O-diethylhydroxyphosphorylmethyl)-N-butylamine

The acid-base and complexing properties of N,N-bis(O-diethylhydroxyphosphorylmethyl)-N-butylamine (H3L) with divalent metals were investigated in aqueous solution via the potentiometric titration method. The formation of 1:1 species has been established. The structure of complex N,N-bis(O-diethylhydroxyphosphorylmethyl)-N-butylamine with copper(II) was determined using an X-ray diffraction method.
