Abstract: 4,4'-Bipyridine(terephthalato)nickel(II), [Ni(C₈H₄O₄)(C₁₀H₈N₂)], exists as poly[₂-terephthalato-₄-terephthalato-bis[(₂-4,4'-bipyridine)nickel(II)]]. Two independent terephthalato groups both occupy positions of 2/m symmetry; one of these groups acts as a ₄ bridge and coordinates four different Ni atoms, one with each of its O atoms. The other one acts as a ₂-bridge and serves as a bidentate chelate for two neighboring metal atoms. The Ni atom lies in a special position of m site symmetry.
