Abstract

The method of isotopic substitution in neutron diffraction is applied to study the coordination environment of Cl^- in a 0.999(3) molal solution of NaCl in fully deuterated ethylene glycol (EG). It is shown that the EG molecules act as monodentate ligands to give a Cl(EG)₄ ^- complex that comprises Cl^- . . . D-O hydrogen bonds which are approximately linear and of length 2.14(3) AA. The results are compared with those obtained for the Cl^- coordination complex in aqueous and methanolic solution. It is found that there is a reduction from approximately=6 to approximately=4 in the number of ligands binding to Cl^- on changing the solvent from water to EG and that, for all three solvents, the Cl^- . . . D-O hydrogen bond is typically linear. The effect of a small hydrogen imbalance between the solutions used for isotopic substitution experiments is briefly considered.
