catena-Poly[[[(4′-phenyl-2,2′:6′,2′′-terpyridine-κ³N,N′,N′′)zinc(II)]-μ-terephthalato-κ²O:O′] monohydrate]

The title compound, {[Zn(C₈H₄O₄)(C₂₁H₁₅N₃)]·H₂O}_n, is a one-dimensional polymeric complex bridged by centrosymmetric dicarboxyl­ate dianions. Each Zn atom is five-coordinate, bonded to two carboxyl O atoms from the dicarboxyl­ate dianions and to three N atoms from the heterocycle, which chelates to the Zn atom in a κ³N,N′,N′′ manner.
