The combination of N-heterocyclic and multi­carboxyl­ate ligands is a good choice for the construction of metal-organic frameworks. In the title coor­dination polymer, poly[bis­{[mu]2-1-[(1H-benzimidazol-2-­yl)meth­yl]-1H-tetra­zole-[kappa]2N3:N4}([mu]4-butane­dioato-[kappa]4O1:O1':O4:O4')([mu]2-butane­dioato-[kappa]2O1:O4)dicadmium], [Cd(C4H4O4)(C9H8N6)]n, each CdII ion exhibits an irregular octa­hedral CdO4N2 coordination geometry and is coordinated by four O atoms from three carboxyl­ate groups of three succinate (butane­dioate) ligands and two N atoms from two 1-[(1H-benzimidazol-2-­yl)meth­yl]-1H-tetra­zole (bimt) ligands. CdII ions are connected by two kinds of crystallographically independent succinate ligands to generate a two-dimensional layered structure with bimt ligands located on each side of the layer. Adjacent layers are further connected by hydrogen bonding, leading to a three-dimensional supra­molecular architecture in the solid state. Thermogravimetric analysis of the title polymer shows that it is stable up to 529 K and then loses weight from 529 to 918 K, corresponding to the decomposition of the bimt ligands and succinate groups. The polymer exhibits a strong fluorescence emission in the solid state at room temperature.

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.
