| Abstract: | We determined the199mHg nuclear quadrupole interaction in the  misfit or superstoichiometric compound Hg
x
TiS2 by time differential perturbed angular correlation. A unique Hg-site withv
Q
=511(1) MHz and  =0.410(4) was observed, irrespective of the Hg-uptake (2/3 x4/3). We propose a model of Hg-Hg zig-zag chains which accounts for these observations as well as for the X-ray diffraction data. |
