The synthesis of a thiourea substituted derivative of tris(pyridyl-2- methyl)amine (TPA) is reported. Two of the three pyridine rings are substituted in the 6-position with benzoylthiourea groups. These thiourea groups undergo intramolecular hydrogen bonding to form six-membered rings which leaves one N-H group available to form hydrogen bonds with other molecules. This reports details how the complexation of this new ligand with transition metal ions yields complexes with differing geometries. Seven co-ordinate Mn(ii) and Cd(ii), six co-ordinate Ni(ii) and five co-ordinate Co(ii), Cu(ii) and Zn(ii) complexes have been isolated. © 2012 The Royal Society of Chemistry.
