The title compound, [Nd2(C4H4O4)(C8H4O4)2]n, was synthesized by hydro­thermal synthesis. The Nd atom is coordinated by four O atoms from four 1,4-benzene­dicarboxyl­ate ligands and four O atoms from three succinate anions, in a distorted square-anti­prismatic coordination geometry. The anti­prisms are bridged by the 1,4-benzene­dicarboxyl­ate and succinate ligands, forming a three-dimensional network. The succinate ion is located on a centre of inversion.

Special details top

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.
