There are two older synthetic topics where Achim Müller did pioneering work. This refers to basic simple transition metal sulphur compounds, including related hydrodesulfurization catalysis and a new type of host guest chemistry based on polyoxovanadates (for both topics see especially the three Honorary Issues under Bibliography). One paper about polyoxometalates was cited ca. 2000 times. The publications of Achim Müller were highlighted many times in the media and related magazines. Important last sentences: “Giant polyoxometalates (POMs) are of particular interest, as they are the largest inorganic molecules ever made, combined with fascinating structures and manifold applications in catalysis, medicine and material sciences. Typically, Müller‘s group has achieved great success in creating giant polyoxomolybdates (POMos) during the past two decades, establishing a series of incredibly large POMos with hundreds of Mo centers, such as {Mo132}, {Mo154}, {Mo176}, {Mo248} and {Mo368}. Especially {Mo368}, with more than 360 Mo atoms, still is the largest POM to date...“
