It's unclear to me whether you think this triangular shape is a problem or
not. To remove confusion, this is not a problem. It's actually expected.
TIPnP water is defined using 3 distances (O-H1, O-H2, and H1-H2), rather
than the two O-H distances and an angle. These are rigid water molecules,
which means that all 3 distances need to be held fixed via SHAKE (or
SETTLE, as is more commonly used for water).
