Study of the complexation reaction between substituted 6,6′-bis(diphenylphosphinoyl)-2,2′-bipyridyls and ions lanthanum
It was found that in the solution for all lanthanide-ligand pairs, only one complex particle is formed with a metal-ligand composition one-to-one in acetonitrile (with a water content of 40±5 ppm) on a Hitachi U-1900 spectrophotometer. The stability constants of complexes were determined by spectrophotometric titration. The results were processed using the HypSpec2014 program.
