Methylcyclopentadienyl Manganese Tricarbonyl - Structure and Synthesis

Structure and Synthesis

The compound is prepared by reduction of bis(methylcyclopentadienyl)manganese using triethylaluminium. The reduction is conducted under an atmosphere of carbon monoxide.

MMT is a so-called half-sandwich compound, or more specifically a piano-stool complex (since the three CO ligands are like the legs of a piano stool). The manganese atom in MMT is coordinated to three carbonyl groups as well as to the methylcyclopentadienyl ring. These hydrophobic organic ligands make MMT highly lipophilic.

Famous quotes containing the words structure and/or synthesis:

    Women over fifty already form one of the largest groups in the population structure of the western world. As long as they like themselves, they will not be an oppressed minority. In order to like themselves they must reject trivialization by others of who and what they are. A grown woman should not have to masquerade as a girl in order to remain in the land of the living.
    Germaine Greer (b. 1939)

    Our art is the finest, the noblest, the most suggestive, for it is the synthesis of all the arts. Sculpture, painting, literature, elocution, architecture, and music are its natural tools. But while it needs all of those artistic manifestations in order to be its whole self, it asks of its priest or priestess one indispensable virtue: “faith.”
    Sarah Bernhardt (1845–1923)
