Reduction of 2-cyanopyridine by sodium in the presence of 3-hexamethyleneiminylthiosemicarbazide produces 2-pyridineformamide 3-hexamethyleneiminylthiosemicarbazone, HAmhexim. Complexes with nickel(II), copper(II) and palladium(II) have been prepared and the following complexes structurally characterized: [Ni(Amhexim)OAc], [{Cu(Amhexim)}2C4H4O4]·2DMSO·H2O, [Cu(HAmhexim)Cl2] and [Pd(Amhexim)Cl]. Coordination is via the pyridyl nitrogen, imine nitrogen and thiolato or thione sulfur atom when coordinating as the anionic or neutral ligand, respectively. [{Cu(Amhexim)}2C4H4O4] is a binuclear complex with the two copper(II) ions bridged by the succinato group in [Cu-(HAmhexim)Cl2] the Cu atom is 5-coordinate and close to a square pyramid structure and in [Ni(Amhexim)OAc] and [Pd(Amhexim)Cl] the metal atoms are planar, 4-coordinate.
