Fukuhara %J The Open Chemical Physics Journal %D 2008 %I %R 10.2174/1874412500801010029] %X Single crystals of Cu4I4(CH3NHCS)2 and CuI(CH3NHCS)2 polymer complexes have been crystallized. Electrical conductivity and X-ray diffraction measurements have been performed on these compounds. The space group symmetries (monoclinic C2/m and triclinic P-1) and the crystal structures are determined at room temperature. It is suggested from the temperature dependence of the conductivity that these complexes become a proton superionic conductor gradually as the temperature is raised. The difference in the conductivity at high temperature between these compounds is discussed with the refined structures. %U http://www.benthamscience.com/open/tocpj/articles/V001/29TOCPJ.htm
