Finding large databases of sphere packings

Part of my research is investigating sphere packings and their properties.I really would like a large database of sphere packings that I could investigate using a program I have written that tells me certain things about the packings. After doing some research I found some online databases but a lot of them haven't been taken care of so they're riddled with dead links. I was wondering if anyone knows of any books or websites that have a lot of sphere packings that I could investigate. Or if there is a way to interpret crystal structures as a sphere packing, seeing how there is a lot of crystal structure databases. 


If anyone is confused as to what kind of data I'm looking I just need coordinates of the centers of spheres and their corresponding radii. These need to form a packing where the spheres are touching like in this paper where the authors have found new bi-disperse packings. Thanks!

I have found a partial answer to finding a large database of sphere packings, thanks to the comment from permeakra! 


So far I have been obtaining .cif files from the large databases of crystal structures online such as, <http://www.crystallography.net/>. Once I have the .cif files I use openbabel to convert those files to .xyz files. From here I have a table that describes a crystal's structure by the x,y, and z coordinates of each particular element for example,


\begin{array}{c|c c c}
\ce{Mg} & 1.01054 & 1.01054 & 1.01054\\\hline
\ce{Al} & 1.01054 & 1.01054 & 1.01054\\\hline
\ce{Al} & 4.04217 & 4.04217 & 4.04217\\\hline
\ce{Mg} & 4.04217 & 4.04217 & 4.04217\\\hline
\ce{O} & 2.11390 & 2.11390 & 2.11390
\end{array}


But my problem from here is that babel has failed to return the ionic radius which I suppose can be retrieved online via wikipedia or something. I posted another question that is more specific to .cif files which expands on this problem which can be found here, [Extracting "Crystal Radii" from a CIF file](https://chemistry.stackexchange.com/questions/34114/extracting-crystal-radii-from-a-cif-file%5C).\


Limitations to this approach include that I can only find 3D sphere packings and it's a rather long and clunky procedure for obtaining lots of sphere packings.
