Controllable assembly of two new Cd(II) coordination polymers based on designed pyridinecarboxylate ligand: From a 2D layer to a 3D pillar-layered framework

Presented here are two new Cd(II) coordination polymers, namely [Cd2(L)2]n · n(H2O) (1) and [Cd2(L)(4,4-bipy)0.5]n (2) (H2L = 5-(pyridin-2-ylmethoxy)-isophthalic acid, 4,4,-bipy = 4,4′-bipyridine). Compound 1 is a 2D layered structure, and compound 2 is a 3D pillar-layered framework.
