چکیده
The asymmetric unit of the title coordination polymer consists of a dinuclear neutral complex mol-ecule of formula [Cu(2)(C(18)H(14)Br(4)N(2)O(2))(2)](n). One of the Cu(II) ions is coordinated in a distorted square-planar geometry, whereas the other is coordinated in a distorted square-pyramidal geometry, the long apical Cu-O bond [2.885 (4) Å] of the square-pyramidal coordination being provided by a symmetry-related O atom creating a one-dimensional polymer along [010]. π-π stacking inter-actions [centroid-centroid distance = 3.783 (4) Å] and short inter-chain Br⋯Br inter-actions [3.6142 (12)-3.6797 (12) Å] are observed.

The asymmetric unit of the title compound, [Cu(2)(C(18)H(14)Cl(4)N(2)O(2))(2)](n), contains two independent Cu(II) ions which are bridged by a pair of 4,4',6,6'-tetra-chloro-2,2'-[butane-1,4-diylbis(nitrilo-methanylyl-idene)]diphenolate ligands, forming a dinuclear unit. One of the Cu(II) ions is coordinated in a distorted square-planar environment and the other is coordinated in a distorted sq...

The asymmetric unit of the title compound, [Ni(C(19)H(16)Br(4)N(2)O(2))], comprises half of a Schiff base complex. The geometry around the Ni(II) atom, located on a twofold rotation axis, is distorted square-planar, which is supported by the N(2)O(2) donor atoms of the coordinated ligand. The dihedral angle between the substituted benzene rings is 23.19 (17)°. In the crystal, a short inter-mole...

The title compound, C(34)H(52)N(2)O(2), is centrosymmetric, the mid-point of the central C-C bond being located on an inversion centre. Intra-molecular O-H⋯N and weak C-H⋯O hydrogen bonds are observed, but no significant inter-molecular inter-actions occur in the crystal structure.
