The molecular modeling parameters support the stability of thiole form of the free ligands in comparing with their thiones by a small difference. The TG analysis for all isolated compounds was briefly discussed. This band is pointed to its use in spectrophotometric analysis for these metal ions. As well as, a new band is shinned in visible region with Sb(III), Bi(III) complexes and Sn(II)-HL2. The electronic spectral analysis displays a lower shift appearance in n → π* charge transfer band in most isolated complexes. The ligand coordinates as bi molecules in some complexes and displays two tautomer forms at the same complex molecule 1H NMR spectra of Sn(II) and Sb(III) complexes were done and comes coincide with IR data. The IR spectra of the complexes support the presence of 2:2 molar ratio (M:HL) with HL1 ligand and 1:1 beside 1:2 with HL2. The IR and 1H NMR spectra of the free ligands display their presence in thiole-thione forms coincide with each other. Sn(II), Sb(III), Pb(II) and Bi(III) are the metal ions used in complexation with two thiosemicarbazide ligands.

Discharge into the environment must be avoided.

Prevent further leakage or spillage if safe to do so. Wear self-contained breathing apparatus for firefighting if necessary. Suitable extinguishing media Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. If swallowed Never give anything by mouth to an unconscious person. In case of eye contact Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
