Abstract: 
The 2D‐coordination polymer 2∞[Ce2Cl6(bipy)4]·py (bipy = 4, 4′‐bipyridine) shows a 5d‐4f centered emission in the soft UV‐B region. It was synthesized via the reaction of anhydrous CeCl3 and 4, 4′‐bipyridine in pyridine under solvothermal conditions. The two‐dimensional sheet structure consisting of 4, 4′‐bipyridine coordinated Ce2Cl6 dimers closes the gap between the known lanthanum 3∞[La2Cl6(bipy)5]·4bipy framework and the 2D networks of the formula 2∞[Ln2Cl6(bipy)3]·2bipy from praseodymium on. They differ in the number of coordinating bipy linkers, which decreases along La > Ce > Pr, with the remarkable observation that lanthanum, cerium, and praseodymium exhibit different network constitutions. The structure of 2∞[Ce2Cl6(bipy)4]·py exhibits a cem topology constituted of double strands, which are diagonally linked by 4, 4′‐bipyridine forming trapezoid cavities in‐between the strands. The cavities contain intercalated pyridine molecules.
