Molybdenum dichloride describes chemical compounds with the empirical formula MoCl₂. At least two forms are known, and both have attracted much attention from academic researchers because of the unexpected structures seen for these compounds and the fact that they give rise to hundreds of derivatives. The form discussed here is Mo₆Cl₁₂. The other molybdenum(II) chloride is potassium octachlorodimolybdate.
