Carbon-13 and proton NMR parameters of neopentyl-and trimethylsilylmethyl-thallium(III) derivatives and the x-ray crystal structure of bis(trimethylsilylmethyl)chlorothallium(III)

Carbon-13 and proton NMR spectra have been determined for organothallium (III) derivatives of the types RTlX2 and R2 TlX (R  (CH3)3CCH2 or (CH3)3SiCH2; X  Cl, Br or O2CCH(CH3)2). The dependence of coupling of 13C and 1H to thallium on the number and nature of R groups is discussed in terms of the Fermi contact mechanism for spinspin coupling.The crystal structure of [(CH3)3SiCH2]2 TlCl has been determined. The compound crystallises in the monoclinic space group P21/n, with a 10.618, b 24.492, c 6.017 Å, β 99.76°. The molecule is dimeric with each four-coordinate thallium atom bonded unequally to two bridging chlorine atoms. The CTlC angle is 168°.
