Catena-Poly[[[aquabis[3-(4-carboxyphenoxy)propionato-κ2 O,O′]zinc(II)]-μ-4,4′-bipyridine-κ2 N:N′] dihydrate

Abstract

In the title compound, {[Zn(C10H9O5)2(C10H8N2)(H2O)]·2H2O} n , the Zn atom, which lies on a twofold rotation axis, has a distorted pentagonal–bipyramidal geometry, involving four O atoms from two 3-(4-carboxyphenoxy)propionate groups, two N atoms from two 4,4′-bipyridine ligands and one water molecule, also lying on the symmetry axis. 4,4′-Bipyridine ligands link adjacent Zn atoms, forming a one-dimensional chain structure. Furthermore, a three-dimensional supramolecular network is buildt up via hydrogen bonding and π–π stacking interactions [centroid–centroid distance 3.9096 (9) Å].
