Thermo Scientific™ Hexacarbonylmolybdenum ≥98%

Hexacarbonylmolybdenum (Mo(CO)₆) is a highly pure organometallic compound composed of a molybdenum atom coordinated to six carbonyl ligands. It is widely utilized in organometallic synthesis, homogeneous catalysis, and precursor chemistry due to its well-defined structure and high volatility. In the research setting, it serves as a molybdenum source for electron beam-induced deposition (EBID) and is a starting material for the synthesis of more complex molybdenum coordination compounds.

This compound is stable in solid form and appears as white to yellow to pale brown crystalline powder. Its carbonyl ligands can be selectively displaced by donor ligands, enabling broad utility in ligand exchange reactions, synthesis of catalysts, and structural studies of transition metal complexes.
