Abstract: The title compound, [Ni(C₆H₁₅NO₃)₂](C₈H₄O₄), consists of a [Ni(H₃tea)₂]²⁺ cation (H₃tea is triethanolamine) and a benzene-1,4-dicarboxylate (terephthalate) anion. The Ni^II atom lies on an inversion centre and exhibits a slightly distorted octahedral coordination geometry formed by two molecules of H₃tea acting as N,O,O'-tridentate ligands; the anion is also centrosymmetric. All the OH groups of H₃tea are involved in an O-HO hydrogen-bonding network with terephthalate O atoms, thus linking the molecular units in chains and forming a two-dimensional infinite network.
