Poly[(μ(3)-5-bromo-nicotinato)(5-bromo-nicotinato)copper(II)].

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.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
