ABSTRACT
In the title coordination polymer, {[Cd2(C10H9O5)2(C10H8N2)2(C3H7NO)2(H2O)2](NO3)2}n, the 3-(4-carboxyphenoxy)propionate monoanion O,O′-chelates to a CdII cation through the aliphatic carboxylate end. One of these O atoms is also connected to the metal cation from an inversion-related metal atom. The five O atoms bonded to the metal centre form a pentagon, above and below which are located the N atoms of the 4,4′-bipyridine molecules. The polycationic ribbon propagates along the b axis of the unit cell. The (aromatic) carboxyl end of the monoanion connects adjacent ribbons into a layer motif in the (102) plane. The nitrate ions are hydrogen bonded to the layer. The geometry of the CdII atom is a trans-N2O5Cd pentagonal bipyramid.
