J.-L. Ren, Y.-L. Fu and Z.-W. Xu

Abstract: The title compound, [Cu(C₈H₄O₄)(C₂H₇N)₂]_n, is a two-dimensional coordination polymer. The Cu atom adopts a square-pyramidal coordination involving two trans dimethylamine molecules and three terephthalate O atoms. There are two distinct terephthalate dianions, both having inversion symmetry. One bonds to four Cu neighbours as a ₄-bridge and one bonds to two Cu atoms as a ₂-bridge. N-HO hydrogen bonds complete the structure.
