Arenedisulfonate-4d-4f 3D heterometallic coordination polymers constructed from 2,7-naphthalenedisulfonate and isonicotinic acid: Structure, luminescence, and magnetic properties

The adjacent elliptical cylinder shaped 2D layers were assembled into 3D coordination frameworks by [SmAg(μ2-O)2] units. (The IN-Ag-IN bridges were omitted for clarity).
