Poly[μ(4)-succinato-μ(2)-succinato-bis[diamminecopper(II)]].

In the title compound, [Cu(C(4)H(4)O(4))(NH(3))(2)](n), the Cu atom is coordinated by the N atoms of two ammonia mol-ecules and four O atoms from three different succinate ligands in a highly distorted octa-hedral geometry. The Cu atom and the C and O atoms of the succinate ligands lie on a mirror plane. Two adjacent CuO(4)N(2) octa-hedra share one common O-O edge, forming a Cu(2)O(6)N(4) biocta-hedron with a Cu⋯Cu separation of 3.524 (2) Å. Neighboring biocta-hedra are connected by bis-unidentate succinate anions in the a-axis direction, while in the c-axis direction biocta-hedra are connected by bis-bidentate succinate anions, leading to an infinite two-dimensional network structure. These networks are further connected along the a-axis direction by hydrogen bonds between ammonia ligands and carboxyl-ate O atoms of neighboring network layers, forming a three-dimensional lamellar 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.
