Abstract

Zinc and cadmium pyridine-2-thionato complexes, M(pyt)2, were prepared by direct electrochemical oxidation of the metal into a solution of pyridine-2-thione (pytH) in acetonitrile. Adducts of type [M(pyt)2L] (L = 2,2′-bipyridine or 1,10-phenanthroline) were obtained by addition of the ligand to the electrolyte phase. X-ray structure determination of [Zn(pyt)2phen] shows the molecule to have a distorted octahedral trans-ZnS2N4 core, with average bond distances of 2.182 Å for ZnN(phen), 2.061 Å for ZnN(pyt) and 2.586 Å for ZnS. The vibrational, 1H and 13C NMR spectra of the compounds are discussed.

      One Zn has ZnS3O and others have ZnN2SO cores. Polymeric ZnII complexes, {Zn(κ1S:1O-pySH-5-COO)2}n 540 [319], {Zn(κ1S:1O-pySH-3-COO)2}n 541 [320] and {Zn(imdtH2)2(S2O3)}n 542 [321], have been reported. In the polymers, 540 and 541, one S and one O are bridging atoms, while in 542, zinc(II) is bonded to two κ1S-imdtH2 thio-ligands and thiosulfate acts as S, O-bridge.

      On the other side, the electrolysis of acetonitrile solutions of these thiones (HL1 and HL2) and bidentate co-ligands such as bipy or phen (L′) in the presence of a zinc anode gave the corresponding heteroleptic complexes [Zn(L1)2L′] and [Zn(L2)2L′]. The crystal structures of the octahedral Zn(II) complexes with 3-trifluoromethylpyridine-2-thionato [L2b]− and bipy or phen [24] are quite similar to that reported for [Zn(L2a)2(phen)] [279] and they exhibit the two monoanionic thionato ligands acting in a bidentate chelating (S,N) manner. In a difference, the structure of the tetrahedral Zn(II) complexes [Zn(L2c)2(bipy)] [24]; [Zn(L1b)2(phen)] [277]; and [Zn(L1c)2(bipy)] [277], which were obtained by electrolysis of acetonitrile solutions of the corresponding heterocyclic thione and the appropriate co-ligand in the presence of a zinc anode, contain the thionato ligand showing a monoanionic monodentate behavior.
