The hydrolysis of the title compound is found to proceed according to the reaction (Chemical Equation Presented) The hydrolysis reactions in solution lead initially to two phosphorus-containing species, 2 and 3. 2 is found to rearrange to 3 and catechol in solution. The crystal structure of 2, (o-HOC₆H₄O)₂P(O)Mn(CO)₅, was determined, and it belongs to the tetragonal system with a space group of I4₁/a. The unit cell parameters are a = 25.145 (10) and c = 12.025 (5) ? and Z = 16. The phosphoryl oxygen is linked to two hydroxyl groups with one intramolecular and one intermolecular hydrogen bond.
