Distorsion of the [Ni(OH2)6]2+ Cation in a Benzenesulfonate—Correlation with Hydrogen Bonds or Intra-Cation Interactions?
In the absence of electronic reasons for distortion and with its ligands idealized as spherical, the hexaaquanickel(II) cation may be regarded as a simple example for octahedral metal coordination. In structurally characterized derivatives, the cation must adopt a lower symmetry in which it may well be distorted. We in...
