title: Crystal structure of bis-{2-[(2-hy-droxy-eth-yl)amino]-ethanol-κ(3) O,N,O'}copper(II) terephthalate.
abstract: The mol-ecular components of the title salt, [Cu(C4H11NO2)2](C8H4O4), are one Cu(II) cation O,N,O'-chelated by two tridentate 2-[(2-hy-droxy-eth-yl)amino]-ethanol ligands, and a terephthalate counter-dianion, located about a centre of inversion. The complex Cu(II) cation is located about a centre of inversion and shows typical Jahn-Teller distortion, with two short Cu-O and two short Cu-N bonds in the equatorial plane and two long Cu-O bonds to the axial atoms. The cations are arranged in sheets parallel to (100), with the centrosymmetric terephthalate anions located between the sheets. Each anion is the acceptor of four O-H⋯O and two N-H⋯O hydrogen bonds, forming a three-dimensional network structure.
