The first lanthanide(III)–iminodiacetate coordination polymer

The first Ln3+–iminodiacetate coordination polymer Ce2(IDA)2(C2O4)(phen)2 (phen = 1,10-phenanthroline) has the 2D-layered structure consisting of the fused 12- and 16-membered rings. The layers are further interacted with each other to form 3D framework through hydrogen bonds and π–π interactions.
