In the title compound, [Cd(C9H6O5)(C10H8N2)(H2O)]n, the CdII atom is coordinated in a distorted octahedral fashion by two carboxylate groups (one in a monodentate and one in a bidentate fashion) from two 4-carboxylatophenoxyacetate anions, two N atoms from a 2,2'-bipyridine ligand and one aqua ligand. The structure is a helix with a long pitch of 16.441 (5) A. A three-dimensional supramolecular network is further constructed through pi-pi stacking and hydrogen-bonding interactions between the helices.
在标题化合物[Cd(C₉H₆O₅)(C₁₀H₈N₂)(H₂O)]ₙ中，CdII原子由两个4 - 羧基苯氧基乙酸根阴离子的两个羧基（一个为单齿配位，一个为双齿配位）、一个2,2'-联吡啶配体的两个N原子和一个水配体以扭曲的八面体方式配位。该结构为一个长螺距为16.441(5) Å的螺旋。通过螺旋之间的π - π堆积和氢键相互作用进一步构建了三维超分子网络。
