Analysis of 6624 crystallographically characterised hydrogen bonds containing M–Cl, C–Cl or Cl– and either HO or HN groups show that M–Cl moieties are good, anisotropic hydrogen-bond acceptors forming hydrogen bonds similar in length to those of the chloride anion, while C–Cl moieties are very poor hydrogen-bond acceptors.
