fac-Acetato-bis(pyrazole) complexes: A systematic study on intra- and intermolecular hydrogen bonds

A systematic study on the hydrogen bonds observed in the crystal structures of fac-acetato-bis(pyrazole) Mo, Mn, and Re complexes reveals that depend on the pyrazole used: dimethylpyrazole complexes show the same pattern of intramolecular hydrogen bonds, whereas intra- and intermolecular are found in the pyrazole complexes.
