Abstract
Studies of the temperature dependence of the electrical resistivity, Hall effect, and magnetic susceptibility indicate that the crystallographic distortion apparent in metallic layered chalcogenides at low temperature is absent after intercalation. In the quasi-two-dimensional superconductor Ta${\mathrm{S}}_{2}$${(\mathrm{pyridine})}_{1/2}$ the measured $c$-axis resistivity is ${10}^{4}$-${10}^{5}$ times the $a$-axis resistivity. However, since the temperature dependence of the $c$-axis resistivity may be represented by a constant times the $a$-axis resistivity, we believe that the $c$-axis resistivity is significantly reduced by shorts and that the intrinsic anisotropy is greater than the measured value of ${10}^{5}$x.
