Good afternoon, I have seen regular shaped arrangements of water molecules in my structures as well, although not at dimer interfaces. I came across this paper which maybe of interest to you.

There are two molecules in the asymmetric unit of this protein. At the dimer interface, the C-termini of both the chains interact with each other with the help of five water molecules that form a pentagon. I have attached an image showing both the chains and stereo image of dimer interface in the inset. I was wondering if there is any significance to this or if there is any relevant literature that explains this behavior.
