In this talk we will discuss the importance of Jim Sullivan's discovery of cation-cation interactions (CCI's) in Np(V) compounds. These interactions give rise to 1D, 2D, and 3D substructures in crystalline solids that provide a mechanism for long-range magnetic coupling. The magnetic ordering in CCI compounds can be ferromagnetic or antiferromagnetic in nature. A computational justification for CCI's will also be presented.
