Five new oxalato and hydrogenoxalato complexes with ZnBr2 have been synthesized and studied by infrared. Discrete structures have been suggested in the basis of spectroscopic data. The environments around the zinc centre being trigonal bipyramidal, tetrahedral, octahedral or monocapped octahedral. The anions behave as monochelating ligands. When the cations and OH group are involved in extra hydrogen bonds, a supramolecular architecture may be obtained.

In the title Schiff base complex, [Cu(C19H18Cl2N2O2)], the CuIIion is coordinated in a distorted square-planar environment by two N atoms and two O atoms of the tetradentate ligand. The dihedral angle between the benzene rings is 36.86 (14)°. In the crystal, molecules are linked into inversion dimers by pairs of weak C—H...O hydrogen bonds. In addition, π–π [centroid–centroid distance = 3.7279 (16) Å] and weak C—H...π interactions are observed.

In the title solvate, [Cu4(μ2-Cl)6(μ4-O)(C4H9NO)4]·2CH3OH, each Cu2+ion in the tetranuclear complex has a trigonal–bipyramidal coordination arising from three bridging chloride ions in equatorial positions and the central μ4-O2−ion and morpholine N atom in axial positions. The morpholine rings adopt chair conformations, with the N—Cu bonds in equatorial orientations. In the crystal, the components are linked by N—H...O and O—H...O and O—H...Cl hydrogen bonds, which generate a three-dimensional network. One methanol molecule is disordered over two sets of sites in a 0.642 (9):0.358 (9) ratio.
