Abstract: The coordination reaction of n-(para-substituted phenyl)nitrogen-hetero-15-crown-5 with Na(l)has been studied by NMR method. The stability constants of these Na(l)-crown complex Compounds have been determined. It has been found that some linear relationships exist between the stability constants and their limit chemical shifts with the correlation equation: logβ=3.95+0.409δNaL.r=0.992

Keywords: crownether stability eonatant limit chemical shift linear relationship
