The chelating properties of 3-amino-I-(8?-quinolyl)-1-thiapropane (2) are discussed. The related ligands 1-(2?-hydroxyphenyl)-6-(8?- quinolyl)-5-thia-2-azapent-1-ene (6), 1-(6?-bromo-2?-hydroxyphenyl)-5- (8?-quinolyl)-5-thia-2-azapent-1-ene (7), 5-(2?-pyridyl)-1-(8?- quinolyl)-1-thia-4-azahex-4-ene (8), and 5-[2?-(6?-acetylpyridyl)]-1- (8?-quinolyl)-1-thia-4-azahex-4-ene (13), and some of their metal complexes are described. The iron(II) sexadentate chelate (17) has been prepared by a metal template synthesis from the amine (2) and glyoxal.

Halide Ligands

A number of cyclic ligands has been prepared by the high-dilution technique. All these ligands have their donor-atoms linked by ethano bridges. Examples of a non-planar quadridentate and three potential sexadentates were prepared. The cyclic quadridentete, 1-oxa-4,10- dithia-7-azacyclododecane (1), formed neutral complexes of the type [MLX2], where M = Co, X = Cl, Br and M = Ni, X = Cl, which are octahedral and presumably have the halide ligands cis to each other. Two of the cyclic ligands, 1,4,10,13-tetrathia-7,16- diazacyclooctadecane (3) and 1,4,7,10,13,16-hexathiacyolooctadecane (4), are the first reported cyclic sexadentates which form octahedral complexes, and the first examples of cyclic sexadentate ligands prepared without the aid of the metal template effect. Complexes of the type [ML](picrate)2, where M = Co, Ni, were prepared from ligands (3) and (4). A third potential sexadentate, 1,10-dioxa-4,7,13,16- tetrathiaoyolooctadecane (5), did not form complexes when treated with MX2, where M = Co, Ni, Fe, Cu and x = Cl, ClO4.

Steric Crowding

A series of linear, five-donor-atom compounds, with nitrogen, sulphur, and oxygen donor-atoms, has been prepared to examine the effects of steric crowding on the formation of octahedral complexes. 1,11-Diamino- 3,9-dithia-6-azaundecane (5) and 4-methyl-1,7-di(8?-quinolyl)-1,7- dithia-4-azaheptane (6) form octahedral complexes with Ni(ClO4)2 or Co(ClO4)2. An increase in the bulkiness of the ligand, as shown by 1,11- bis(dimethylamino)-3,9-dithia-6-azaundecane (7), led to the formation of five-coordinate or partially five-coordinate cobalt(II) and nickel(II) complexes. With 1,11-bis(diethylamino)-3,9-dithia-6- azaundecane (8), a very hindered ligand, no pure cobalt(II) or nickel(II) complexes could be isolated. Several other hindered compounds containing all sulphur, or sulphur and oxygen, central donor- atoms did not form pure complexes when treated with Co(ClO4)2 or Ni(ClO4)2.
