What they have found is the two non bonded electrons pairs sort of merge between where they thought the two non bonded electrons were, much closer to the oxygen atom.

When water forms ice then the tetrahedral sort of returns. But when water is hydrogen bonded to some proteins, the water is triangular. The bent shape allows the hydrogen to share the electrons on another water.

Side note for you (Bond, H-bond): 2 different groups (one definitely published in the
Journal of Magnetic Resonance, the other I am not sure of at this point) are working on room temperature solid state water in various materials (it started with concrete).
One has approached this from the experimental angle, observing tetrahedral jumps with NMR, another has approached it from the theoretical angle calculating that tetrahedral jumps occur using mathematical physics simulations. Not all that sure who/what the other group is, I just know that someone approached it from the theoretical angle (I might be able to dig around and find who it is...).
