Poly[trans-diaquabis[μ-3-(3-pyridyl)propionato-κ2N,O]cadmium(II)]

The title compound [Cd(L)2(H2O)2]n (L = 3-pyridinepropionic acid, C8H8NO2), is a two-dimensional coordination polymer in which the CdII ion lies on an inversion center and is coordinated in a slightly distorted octahedral environment. The aqua H atoms are involved in intermolecular O–H...O hydrogen bonds, which extend the two-dimensional structure to a three-dimensional architecture. The Cd...Cd separation within a layer is 9.0031 (1) Å
