Summary
Mono-, bis- and tris-ligand nickel(II) and cobalt(II) complexes with 4 amino-3-alkyl-5-thio-1,2,4-triazolines (HRL) (R=H, Me, or Et) and 4-amino-5-oxo-3-thioxo-6-methyl-2,3,4,5-tetrahydro-1,2,4-triazine (HL') have been prepared and characterized. In these complexes both HRL and HL' are in the neutral thione form. Nickel(II) and cobalt(II) complexes with mononegative thiolate ligands have been also isolated.
The reaction of HL' with copper(II) salts in a molar ration of 1∶1 results in the formation of [Cu(HL')X] (X=Cl or Br) and Cu(L')X (X=NO3 or CH3COO). However, in the presence of a large excess of HL' the reaction proceeds with partial reduction of CuII and both [Cu(HL')X2] and [Cu(HL')2]X have been isolated and characterized. The mechanism of copper(II) reduction by HL' is discussed.
