Bottom Line: 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.

ABSTRACT
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.
