text: From interpretations of the anisotropies in the Compton profile of ordinary ice that the hydrogen bond is partly covalent.
text: The hydrogen bond in water is part (about 90%) electrostatic and part (about 10%) electron sharing, that is covalent  (see discussion) and may be approximated by bonds made up of covalent HO-Hδ-····δ+OH 2 , ionic HOδ--Hδ+····Oδ-H 2 , and long-bonded covalent
text: In this symmetric form (the 'Zundel' cation, shown right, lifetime ≈ 0.5 ps ), all O-H bonds are the same length (0.95 Å) except the two involved in the hydrogen bond, which are covalent and equally-spaced (1.18 Å; similar to that in ice-ten, and as found by neutron diffraction in some crystals midway between the oxygen atoms [118a], such as the dihydrates of HCl and HClO 4 , for example, [H 5 O 2 +][ClO 4- ]).
