Depolymerization reactions of organostibonic acids with protic ligands have been investigated. Reaction of arylstibonic acids with 8-hydroxyquinoline (8-HQ), or {2-[1H-pyrazol-5(3)-yl]naphthalene-1-ol} (H(2)naphpz) in a 1 : 1 stoichiometry in refluxing toluene affords adamantane-like L(4)(RSb)(4)O(6) clusters [(p-XC(6)H(4)Sb)(4)(O)(6)(Q)(4)] (where X = Cl (1), Br (2), QH = 8-hydroxyquinoline), ...

1-(8-Hydroxy quinolin-2yl-methyl) thiourea ligand (HTF) was synthesized from 8-hydroxyquinoline and thiourea with formaldehyde by condensation method in N,N-dimethyl foramide medium. The metal complexes Zn(II), Cu(II), Ni(II) and Co(II) were prepared using the 1-(8-hydroxy quinolin-2yl-methyl) thiourea as ligand. The ligand and its metal complexes were characterized by elemental analysis, FT-IR...
