| Description | We report here the first crystallographic evidence for a hydrogen-bonding-like interaction between a water molecule and a d8 metal ion, based on neutron diffraction. According to our HF and MP2 calculations, the interaction is almost entirely dispersion-driven and thus represents a limiting case of hydrogen bonding. We speculate that for square-planar d8 metal complexes of zero or negative charge, such hydrogen bonding with water molecules might affect the solvolysis mechanism and be at the origin of anomalously slow aquation rate constants previously reported for some PtII complexes. |
