This kind of tessellation is not very interesting in itself, but has been invented and used by many authors independently as basis for more advanced designs. I also came up with this design at some point and used it for my Saturn Tessellation.
It seems different names are in use for the molecule, but the name I picked up is Four-Sink-Base, used by Meenakshi Mukerji. There is an interesting discussion about where this model and its name came from in comments below this flickr post.
