✦ Synopsis

Template reactions are described in which pentanedione or salicylaldehyde are reacted with aminoethanethiol in the presence of Ni(OAc) 2 β€’4H 2 O resulting directly in the reported nickel complexes. In both reactions a tridentate chelating N,O,S ligand is formed, which in the complexes is dianionic with one thiolate and one alkoxide donor atom. Starting from pentanedione a dinuclear product is obtained with bridging thiolate ligands. A folding angle of 107.1(2)Β°is observed between the planes Ni1 S1 S2 and Ni2 S1 S2. Starting from salicylaldehyde a trinuclear compound is obtained, in which the three nickel ions are connected to each other by the thiolate donor atom from each ligand, resulting in a six-membered ring consisting of alternating thiolate and nickel atoms.

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. Th
