The power of the chelate effect: Syntheses and crystal structures of three discrete complexes containing 20-membered chelate rings derived from an “extended-reach” ligand
摘要:
Reaction of 1,3-di(2-(4-(2-quinolyloxy)phenyl)prop-2-yl)benzene (1) with copper(II) chloride and various silver(l) salts consistently generates discrete mononuclear complexes that involve the ligand adopting a common conformation in which it consistently folds into a U-shape and generates large 20-membered chelate rings in which the ligand acts in a trans-spanning mode.
