Synthesis, Characterization of Complexes of N-benzoyl-n'-2-nitro-4-methoxyphenyl-thiourea with Cu, Ni, Pt, Pd, Cd and Hg
Tóm tắt
A series of coordination complexes with the compositions CuL, NiL×2H2 O, ML2 Cl2 (M =Pt(II), Hg(II)) and M(L-H)2 (M =Pd(II)), Cd(II)), where L =N-benzoyl-N'-2-nitro-4-methoxyphenylthiourea, were synthesized and characterized by conductance, EPR, IR and electronic spectral studies and thermogravimetric analysis. The IR and electronic spectra suggest coordination through the thiocarbonyl S and carbonyl O in the Pd(II) and Cd(II) complexes, and S bonding for the Pt(II) and Hg(II) complexes. The Cu(II) and Ni(II) complexes have polymeric structures in which the ligand is coordinated via the N, O and S atoms.
