Abstract

A synthesis for the new tetrapodal ligands [N,N′-dimethyl-N,N′-di(quinoline-2-methyl)]-1,2-ethylene diamine (LO₁ (3a) and [N,N′-dibenzyl-N,N′-di(quinoline-2-methyl)]-1,2-ethylene diamine (L₂) (3b) and for the related octahedral complexes (L_1,2)FeCl₂ (6a and 6b) and (L_1,2)CoCl₂ (7a and 7b) is given. The solid state structures of 3b and 6a have been determined. Three different modes are possible for a tetradentate coordination of L_1,2 to FeCl₂ or CoCl₂. In 6a the ligand adopts a single chiral geometry around the ClFeCl plane.
