چکیده
In the title compound, [Cd(3)(C(16)H(10)O(4))(3)(C(3)H(7)NO)(2)](n) or [Cd(3)(SDA)(3)(DMF)(2)](n) (H(2)SDA is trans-stilbene-4,4'-dicarboxylic acid and DMF is dimethyl-formamide), the linear dicarboxylate ligand forms a two-dimensionally layered metal-organic network with the relatively uncommon 3(6) topology. The structure reveals trinuclear secondary building units and has an octa-hedral geometry at a central metal ion (occupying a symmetry site) and tetra-hedral geometries at two surrounding symmetrically equivalent metal ions lying on a threefold axis. The six-connected planar trinuclear Cd(II) centers, Cd(3)(O(2)CR)(6), play a role as potential nodes in generation of the relatively uncommon 3(6) topology. The coordinated DMF unit is disordered around the threefold axis.
