Tetra-kis(μ(2)-2-methyl-3,5-dinitro-benzoato-κO:O)bis-[aqua-copper(II)] tetra-hydrate.

The title compound, [Cu(2)(C(8)H(5)N(2)O(6))(4)(H(2)O)(2)]·4H(2)O, forms a centrosymmetric paddle-wheel-type dimer with an intra-molecular Cu⋯Cu distance of 2.6540 (4) Å. The Cu(II) atom is in a square-pyramidal coordination environment formed by four O atoms of four carboxyl-ate groups and one water mol-ecule, which is located in the apical position. The carboxyl-ate groups are twisted relative to the benzene rings by 11.09 (16) and 45.55 (19)°. The nitro groups are not coplanar with the parent aromatic rings [dihedral angles = 16.2 (3)-51.45 (14)°]. O-H⋯O hydrogen bonds between the coordinated water mol-ecules and one of the nitro groups, as well as π-π stacking inter-actions [centroid-centroid distance = 3.5764 (12) Å] between the benzene rings, assemble the complex mol-ecules into a one-dimensional polymeric structure which is further extended into a three-dimensional polymeric network via O-H⋯O hydrogen bonds involving the water molecules of crystallization.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
