Abstract

A novel family of nonadentate ligands based on the (5, 6-diphenyl-1, 2, 4-triazin-3-yl)- picolinamide donor moiety has been synthesized from simple starting materials in high yield and purity. This group of ligands is an addition to the neutral nonadentate group but the first to incorporate 1, 2, 4-triazine. Their ability to extract a select group of lanthanides from acidic aqueous solution has been correlated to their ability to meet the ideal trigonal tricapped ...
