Abstract:

Diamagnetic niobium and tantalum complexes of general formula [M(η5-C5Me5)(dithiolene)2] have been prepared (M = Nb, dithiolene = dddt2 (5,6-dihydro-1,4dithiine-2,3-dithiolate) (1); M = Ta, dithiolene = dddt2 (2); M = Nb, dithiolene = dddt2 and dmit2 (1,3-dithiole-2-thione-4,5-dithiolate) (3)). All these complexes exhibit temperature-dependent 1H NMR spectra which result from a fluxional behavior of the dithiolene ligands. Their redox properties have been investigated by cyclic voltammetry and reversible oxidation processes involving the dithiolene ligands have been evidenced for the compl

Owing to a wide range of coordination modes that can be adopted by 1,1-dithiolate anions, such as monodentate, chelating, μ2-bridging, μ3-bridging, etc., there exists a rich diversity in supramolecular assemblies for these compounds, including examples of zero-, one-, and two-dimensional architectures.

Sensitized photooxidation of 4-phenyl-1,2-dithiolane 1 has been studied. Reacting it with 0.5 mole equivalents o f singlet oxygen, a mixture of 1, 4-phenyl-1,2-dithiolane-1-oxide 2, and 4-phenyl-1,2-dithiolane-2-dioxide 3 is produced. Using one mole equivalent of singlet oxygen, 3 is obtained in high yields. The chemical oxidation of 1 using H2O2/HOAc yields pure 2. With 2 a diastereoselectivity of 10:1 is observed. The oxidative addition of 1 to L2Pt(η2-C2H4)[L=PPh3 (4), 1/2 dppe (5)] leads to the 3-phenyl-propane dithiolato complexes 6a,b. The platinum(O) com pound 4 reacts with 2 to give th

Abstract:

The new bis(dithiolate) complexes Mo(1,2-S2-4-R-C6H3)2(PMePh2)2, R = H, Me, are readily synthesized from three different types of starting materials: trans-Mo(N2)2(PMePh2)4, MoCl4(PMePh2)2, and MoOCl2(PMePh2)3. The 31P NMR spectra of the dithiolate complexes at low temperature are consistent with a cis stereochemistry of the PMePh2 ligands and isomerism with respect to inversion at sulfur and relative positioning of the methyl groups on the chelating 1,2-S2-4-Me-C6H3 ligands. The singlet in the 31P NMR spectrum at room temperature arises from rapid interconversion of these isomers. Substitutio

Abstract The titanocene dithiolenato chelates Cp′2Ti(S2C6H3CH3-4) and CpCp′Ti(S2C6H3CH3-4) (Cp = η5-C5H5, Cp′ = η5-C5H4CH3) were prepared by reaction o f Cp′2TiCl2 or CpCp′TiCl2 with equivalent amounts of 1,2 -(LiS)2C6H3CH3-4. The structure and the conform ational mobility of the η5-bonded and of the chelating ligands of the dithiolenato complexes are discussed on the basis of their temperature-dependent 1H NMR spectra. The mass spectra show metastable transitions for the fragmentation processes.

The title compound, hexakis[μ3-1,2-bis(trifluoromethyl)ethene-1,2-dithiolato]-octahedro-hexapalladium(II), [Pd(C4F6S2)]6, crystallizes as its benzene solvate, [Pd(tfd)]6·2.5C6H6, where tfd is the dithiolene S2C2(CF3)2. The molecular structure of [Pd(tfd)]6is of the hexametallic cube type seen previously in three examples of hexameric homoleptic palladium monodithiolene structures. All structures have in common: (a) the cluster closely approximates a cube containing six PdIIatoms, one at the centre of each cube face; (b) 12 S atoms occupy the mid-points of all 12 cube edges, providing for each

Abstract The ability of the aromatic tetraaldehyde l,2-bis(4-tert-butyl-2,6-diformylphenylsulfanyl)-ethane (1) to function as a precursor in the preparation of binucleating hexaamine-dithiolate ligands has been investigated. Reductive amination of compound 1 with bis(aminoethyl)amine under medium-dilution conditions affords the macrobicyclic hexaamine-dithioether compound L1. Deprotection of the [1+2] condensation product gives the corresponding 24-membered hexa-amine-dithiophenol ligand H2L2. The formulation of L1 as a macrobicyclic amine-thioether was confirmed by an X-ray crystal structure

Abstract:

We have attached a photochromic spiropyran to the surface of CdSe–ZnS core–shell quantum dots, relying on a dithiolane anchoring group. In the resulting assembly, the reversible interconversion of the photochromic component activates and suppresses an energy transfer pathway from the excited quantum dots to the coloured state of the ligand. As a result, the luminescence intensity decreases by 45% with the photoinduced colouration of the spiropyran and returns to the original value after the thermal reisomerization of the ligand.

As 1,2-dithiolate ligands 1,2-dithiooxalate (dto) and 1,2-dithiosquarate (dtsq) were used. It follows from the IR spectra that the multidentate dithiolate ligands coordinate exclusively via their sulfur atoms forming an MN2S2 coordination sphere. The central metal ions (M) are Cu2+, Ni2+, Pd2+, Pt2+, and Zn2+. The complex [CuII(bpy)(dto)] could be studied by EPR spectroscopy and was measured as powder, diamagnetically diluted in the isostructural [NiII(bpy)(dto)] host structure. T

Complex 3 can be converted to the zinc amine function [Zn(pytBuN2H2Me2S2)] (5) without losing the metal center using NaBH4 in methanol solution. On the other h
