Chemical Structure Thallium (atomic symbol: Tl, atomic number: 81) is a Block P, Group 13, Period 6 element with an atomic weight of 204.38.The number of electrons in each of thallium's shells is 2, 8, 18, 32, 18, 3 and its electron configuration is [Xe] 4f5d6s6p. The thallium...
These ions are examples of complexes containing a metal with an empty valence shell (s掳 electron configuration). Such compounds are characterized by low-energy ligand to metal charge transfer (LMCT) bands in their absorption spectra. Reductive elimination initiated by LMCT excitation seems to be ...

A thallium atom has 81 electrons, arranged in the electron configuration [Xe]4f145d106s26p1; of these, the three outermost electrons in the sixth shell are valence electrons. Due to the inert pair effect, the 6s electron pair is relativistically stabilised and it is more difficult to get t...
707 Although the solutions were prepared from the thallium(III) salt Tl(OTf)3, the 205Tl NMR measurements and the absence of typical Tl(III)S bond distances suggest that the metal ion in the solution is in the monovalent form, i.e., thallium(III) has been completely reduced to Tl(I)...

Different from closed shell species, we also use the complete open shell configuration interaction (COSCI) method to calculate the ground-state energies of opened shell species (Tl0 and Pb0 with the electron configuration as [Xe]4f145d106s26p1 and [Xe]4f145d106s26p2, respectively ). With ...
Metals for which compounds of formula I may be prepared via reaction 1 include, for example, Zn, Al, In, Ti, Zr, V, Ga, Sc, Y, La, the lanthanides, Bi(III), and especially Zn, Al, In, Ti, Zr, and V. Exemplary R groups include ispropyl and n-butyl. MX1 n +n ZOH+n NR3...
The relative configuration of 3-(2,3dihydro-1H-inden-3-yl)-2-methyl-3-oxopropyl 4-bromobenzoate was assigned by X-ray crystal structure analysis, allowing additional insights into the mechanism of the thallium(III)-promoted oxidative rearrangement of homoallylic alcohols. The reaction of primary ...
