Polynuclear Gold(I) Complexes of Mercaptocarboxylic Acids
Gold(I) Thiolates, (Benzylthiolato)gold(I) Complexes, Gold(I) Mercaptocarboxylates, Polynu clear Gold(I) Complexes In a search for air-stable and water-soluble mercapto compounds of gold with a high gold content, benzylthiol, a-mercapto-acetic acid, /3-mercapto-propionic acid, and thiosalicylic acid were converted into aurated sulfonium salts by treatment with reagents of the type [(R^PjAufiO*...
متن کاملPolynuclear diorganotin(IV) complexes with arylhydroxamates: Syntheses, structures and in vitro cytotoxic activities.
Series of polynuclear diorganotin(IV) complexes with di-halogenbenzohydroxamate ligands (substituents=2,4-Cl(2), 2,4-F(2), 3,4-F(2), 2,5-F(2), 2,6-F(2)), formulated as the polymeric [R(2)SnL](n)a (1:1) and the tetranuclear [R(4)Sn(2)(HL)(2)(L)](2)b (2:3) (HL=arylhydroxamate), were prepared and characterized by FT-IR, (1)H, (13)C, (119)Sn NMR spectroscopies, elemental analyses and melting point ...
متن کاملDiscrete polynuclear manganese(ii) complexes with thiacalixarene ligands: synthesis, structures and photophysical properties.
The synthesis, crystal structure and photophysical properties of the new compound [Mn4(ThiaSO2)2F][K(18-crown-6)], ThiaSO2 = p-tert-butylsulphonylcalix[4]arene, are presented and compared to the ones of [Mn4(ThiaSO2)2F]K. The strong orange luminescence is attributed to the Mn(2+) centred (4)T1→(6)A1 transition. Its temperature and pressure dependence and quenching by molecular dioxygen are repo...
متن کاملPolynuclear lanthanide hydroxo complexes: new chemical precursors for coordination polymers.
The synthesis of hexanuclear lanthanide hydroxo complexes by controlled hydrolysis led to polymorphic compounds. The hexanuclear entities crystallize in four different ways that depend on the extent of their hydration. The four structures can be described as hexanuclear lanthanide entities with formula [Ln(6)(mu(6)-O)(mu(3)-OH)(8)(NO(3))(6)(H(2)O)(12)](2+). Two additional NO(3)(-) ions intercal...
متن کاملPolynuclear palladium complexes with biogenic polyamines: AFM and voltammetric characterization.
Polynuclear Pd(II) complexes with biogenic polyamines present great potential clinical importance, due to their antiproliferative and cytotoxic activity coupled to less severe side-effects. The adsorption process and the redox behaviour of two polynuclear palladium chelates with spermine (Spm) and spermidine (Spd), Pd(II)-Spm and Pd(II)-Spd, as well as of their ligands Spm and Spd, were studied...
