Single crystals of HMTTeF·Xn ( X=Cl, Br, I, PF6, AsF6, and ClO4) were prepared by the electrochemical method. The in-plane conductivities of the plate-like chloride, bromide, and iodide crystals were found to show metallic temperature dependence in the range from 300 to ca. 100 K, and to maintain fairly high values even at 5 K. In these metallic salts, HMTTeF was found to be in the state of mixed-valency by Raman spectroscopy.
