Abstract: The title compound, [Cu(C₈H₄O₄)(C₂₁H₁₅N₃)]·C₈H₆O₄, consists of polymeric chains in which the terpyridine heterocycle chelates to the Cu atom in an N,N',N''-tridentate manner; the Cu atoms are also covalently bonded through the two singly-bonded carboxyl O atoms of the dicarboxylate dianions to give rise to a chain structure. An additional terephthalic acid molecule is hydrogen bonded to the chains. The asymmetric unit contains halves of two different half-molecule terephthalate ions; in each case, the complete ions are generated by inversion symmetry.
