Abstract

New hydrophobic, tetradentate nitrogen heterocyclic reagents, 6, 6′-bis-(5, 6-dialkyl-1, 2, 4- triazin-3-yl)-2, 2′-bipyridines (BTBPs) have been synthesised. These reagents form complexes with lanthanides and crystal structures with 11 different lanthanides have been determined. The majority of the structures show the lanthanide to be 10-coordinate with stoichiometry [Ln (BTBP)(NO3) 3] although Yb and Lu are 9-coordinate in complexes with ...
