✦ Synopsis

The six-step synthesis of a chiral, pentadentate dihydrosalen ligand, carrying a mercaptomethyl group as additional binding site, is described. When this ligand was treated with nickel(I1) salts, a planar tetracoordinated nickel chelate was obtained, and not the expected pentacoordinated species. This complex was fully characterized, including X-ray crystallography. The crystal structure revealed that the nickel ion is coordinated by the thiolate anion, both the amine and Transition metal complexes of oligodentate ligands with N, 0, and S heteroatoms play an important role as models 4 * la3: R = Ph; 1 b-): R = CH2Ph 'hacernic mixture
