摘要：

We investigated the coordinative behaviour of the phosphanylthiosemicarbazone ligand 2-[2-(diphenylphosphanyl)benzylidene]-N-phenylthiosemicarbazone (HLPPh) towards coinage M-I metal ions (M = Cu, Ag, Au). The complexes obtained, with formulae [Cu(HLPPh)(2)]Br (1), [Cu(HLPPh)(2)]I center dot H2O (2), [Ag(HLPPh)(NO3)]center dot 3H(2)O (3) and [Au-2(HLPPh)(2)]center dot 3CH(3)O(H) (4), were satisfactorily characterized by elemental analysis, IR and H-1/P-31 NMR spectroscopy as well as ESI mass spectrometry. In addition, we obtained the crystal structure of the complex [Au-2(mu-S,P-HLPPh)(2)]Cl-2 (5), which is the first example of a homoleptic thiosemicarbazone Au-I complex, because the Au-I ion has been stabilized by exclusively using a phosphanylthiosemicarbazone ligand. We also performed preliminary luminescence studies for these complexes, as well as the screening of its biological activity against human cervical carcinoma (HeLa) cells.
