The i.r. spectra of the OH and OD stretching vibrations of isotopically dilute HDO in barium chloride dihydrate have been studied at 28° and −175°. The spectra show that three of the OH groups of the water molecules form hydrogen bonds of similar strength while the fourth OH group is much more weakly bonded, in agreement with neutron diffraction studies on the crystal. The i.r. results indicate that the strongest hydrogen bond formed in this hydrate has the same enthalpy as the hydrogen bonds present in ice.

Answer:
Two water hydrogen bonded water molecule(s) are associated with Bacl2.2H20
Explanation:
Interstitial water association
Interstitial water is water that is present in the interstitial sites of a crystal lattice. Hydrogen-bonded water is the water that that is linked to some other ion by hydrogen bonding.
Bacl2.2H20
Interstitial water molecules can be found in BaCl X 2 ⋅ 2 H X 2 O salt. Between the first and second solvation shells, water molecules are primarily trapped. It can be found in the crystal lattice's interstitial locations.
