چکیده
The title coordination polymer, [Cu(C(6)H(3)BrNO(2))(2)](n), is composed of two structurally similar two-dimensional coordination polymers (twin layers). Both of them have the same chemical composition but they display different bond lengths and angles. In each layer, two N atoms and four carboxyl-ate O atoms from the bridging 5-bromo-nicotinate ligands and four carboxyl-ate O atoms from the terminal 5-bromo-nicotinate ligands bind to two Cu(II) atoms to form a dinuclear paddle-wheel-like pattern. Adjacent paddle wheels are further linked by bridging 5-bromo-nicotinate groups to generate a two-dimensional coordination polymer; neighboring twin-like layers are finally stacked through π-π stacking interactions between adjacent pyridine rings [perpendicular distance of 3.626 (2) Å] in a 'sandwich' manner, thus generating a three-dimensional supra-molecular structure.

In the title compound, [Nd(2)(C(6)H(3)BrNO(2))(6)(H(2)O)(4)]·2H(2)O, the Nd(III) ion is coordinated by nine O atoms from one chelating 5-bromo-nicotinate ligand, four bridging 5-bromo-nicotinate ligands and two water mol-ecules, exhibiting a distorted three-capped triangular-prismatic geometry. Two Nd(III) ions are bridged by four carboxyl-ate groups in bi- and tridentate modes, forming a centr...

The title complex, [Cu{μ3-O2CC6H3(NO2)2-3,5}(μ-OH)] n , features zigzag chains in which successive pairs of Cu(II) atoms are connected by OH bridges and bidentate carboxyl-ate ligands, leading to six-membered Cu(O)(OCO)Cu rings. The zigzag chains are connected into a three-dimensional architecture by Cu-O(nitro) bonds. The coordination geometry of the Cu(II) atom is square-pyramidal, with the a...

The asymmetric unit of the title polymeric mononuclear Cu(II) complex, [Cu(C2N3)2(NH3)2] n , contains one half-mol-ecule, the complex being completed through inversion symmetry, with the Cu(II) atom situated on the centre of symmetry. The coordination polyhedron around Cu(II) is a Jahn-Teller-distorted [CuN6] octa-hedron. The terminal N atoms of two dicyanamide ligands and two ammine ligands fo...
