Abstract
In the crystal structure of the polymeric title complex, [Cd(C11H10O4)(C10H8N2)]n, the CdII cation is chelated by one 2,2-bipyridine ligand and two carboxyl groups from two trimethylisophthalate (TMIPA) anions, and is further coordinated by one carboxylate O atom from a third TMIPA anion, forming a distorted pentagonal–bipyramidal geometry. Each TMIPA anion bridges three CdII cations, forming polymeric complex sheets parallel to (001). Weak C—H⋯O hydrogen bonding occurs between adjacent sheets.

The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry
