Novel bis(diethylenetriamine)thallium(III) complex. Synthesis and characterization in pyridine solution and in solid
摘要:
A new complex of thallium(ill) with the nitrogen donor ligand diethylenetriamine (dien) has been prepared and characterized by multinuclear NMR (H-1, C-13. Tl-205), infrared and Raman spectroscopy. and X-ray diffraction. In solution, the symmetric s-facial isomer of [Tl(dien)(2)](3+) is formed. This is a fluxional molecule even at low temperature (235 K): therefore, the different rotamers cannot be observed separately. A complete characterization of the complex is given from its non-trivial NMR spectra. The crystal structure of [Tl(dien)(2)](ClO4)(3).H2O shows u-facial geometry. where the coordination environment around thallium can be described as a distorted trigonal prism.

On the other hand, complex 3 reacts with the ylide Ph(3)P=C(H)CN (1:2 molar ratio) giving [Pd[C(H)PPh(3)](2)CO}[NC-C(H)=PPh(3)](2)](ClO(4))(2), 8, which contains two N-coordinated ylides, and with NBu(4)OH (1:1) to give [Pd(&mgr;-OH)[C(H)PPh(3)](2)CO}](2)(ClO(4))(2), 9. The reaction
alkylating agents gives the known σ- and η- organocobalt(I) derivatives, and reactions with TIClO4 in the presence of various amounts of different mono- and bi-dentate phosphines give the cationic tricarbonyl [Co(CO)3(PPh3)2]+, dicarbonyl [Co(CO)2(PMePh2)3]+ and monocarbonyl [Co(CO)L4]+ complexes (L4 = 4P(OMe)3, 2 dppe and 2dppm). The dppm complex crystallizes in the monoclinic space group P21/c with

The reactions of thallium(III) with someketones in the presence and absence of Cl−, Br−, CN−, CH3COO− and CF3COO− ions in acidic aqueoussolution, and the stabilities of the resulting monoorganothallium(III) species in solution have been examined. the rate-determining step in the formation of these compounds is the acid-catalyzed enolisation of the ketones. The formation reactions are reversible:

half-life of the process being in the 109 h range at neutral pH. The solution dynamics of [Tl(dota)]− were investigated using 13C NMR spectroscopy and DFT calculations. The 13C NMR spectra recorded at low temperature (272 K) point to C4 symmetry of the complex in solution, which averages to C4v as the temperature increases. This dynamicbehavior was attributed to the Λ(λλλλ) ↔ Δ(δδδδ) enantiomerization process

Exposure of thallous salts to high-energy radiation usually yields TlII centres together with paramagnetic centres derived from the anions which show strong charge-transfer interaction with neighbouring thallous ions. Previous work on thallous acetate and nitrate is extended to the perchlorate, and to the corresponding TlIII salts. The latter all gave TlII but centres derived from the anions generally
