The structures of the solute complexes existing in methanolic CuCl<SUB>2</SUB> solutions with concentrations of 1.055–3.250 mol dm<SUP>−3</SUP> were investigated by X-ray diffraction analysis. The solute complexes which were predominantly present could be formulated as [CuCl<I><SUB>n</SUB></I>(CH<SUB>3</SUB>OH)<SUB>6–<I>n</I></SUB>] (<I>n</I>=1–3); they have an axially elongated octahedral structure including Cl<SUP>−</SUP> at the equatorial site. The Cu-O bond distance was 2.230–2.238 Å. Methanol molecules were coordinated at the equatorial site with the Cu-O bond distance of 1.926–1.950 Å and at the axial site with that of 2.423–2.473 Å. When the initial concentration of CuCl<SUB>2</SUB> was kept within the range examined here, almost all of the Cu<SUP>2+</SUP> ions formed chloro complexes.
