Complexes of Ag(I), TI(I), Zn(II), Hg(II), Cd(II), Pd(II), Co(II) and Ni(II) with 4-[(4-dimethylamino-benzylidene)-amino]-5-ethyl-2,4-dihydro-[1,2,4]triazole-3-thione (HDEDT) and 4-[(benzylidene)amino]-6-(t-butyl)-4H-[1,2,4]triazine-3-thione-5-one (HBBTT)

The synthesis and characterization of complexes of Ag(I), Tl(I) Zn(II), Hg(II), Cd(II), Pd(II), Co(II) and Ni(II) with 4-[(4-dimethyl-amino-benzylidene)-amino]-5-ethyl-2,4-dihydro-[1,2,4]triazole-3-thione (HDEDT) and 4-[(benzylidene)amino]-6-(t-butyl)4H-[1,2,4] triazine-3-thione-5-one (HBBTT) are described. Octahedral structures are proposed for the Co( II) and Ni( II) complexes, tetrahedral ones for the Hg( II), Zn( II) and Cd( II) complexes, linear polymeric structures for the Ag( I) and Tl( I) complexes and a square-planar structure for the Pd( II) complex. The ligand coordinates to the metal ions through the thiol sulfur after deprotonation and with the nitrogen of the azomethine group.
