The crystal structures of bis{l_brace}2,4-dibromo-6-[(2-hydroxyethylamino)-methyl]phenolato{r_brace}copper (I), bis{l_brace}2,4-dichloro-6-[(2-hydroxyethylamino)-methyl]phenolato{r_brace}copper (II), and bis{l_brace}2-[(2-hydroxyethylamino)-methyl]-4,6-dinitrophenolato{r_brace}copper (III) in which the metal atom is located at the center of symmetry are determined using X-ray diffraction. Crystals of compounds I and II are isostructural. The copper atom in the structures of compounds I and I coordinates two singly deprotonated bidentate molecules of the ligand through the phenol oxygen atoms and the azomethine nitrogen atoms with the formation of a distorted planar square. In the crystals, complexes I and II form one-dimensional infinite chains along the b axis. In the structure of compound III, the coordination polyhedron of the central atom is an elongated tetragonal bipyramid with the base formed by the azomethine nitrogen atoms and the phenol oxygen atoms. Both vertices of the bipyramid are occupied by the oxygen atoms of the amino alcohol groups of the neighboring complexes, which are related to the initial complex through the center of symmetry. In turn, the oxygen atoms of the alcohol groups of the initial complex are located at the vertices of the coordination bipyramids of the metal atoms of the neighboring centrosymmetric complexes, thus forming infinite polymer chains along the a axis.
