In this study, a novel organic-inorganic hybrid compound with AgNO3 and 2,3-pyridinedicarboxylic acid (H(2)pydc), [Ag-2(mu(6)-pydc)](n) (1) has been synthesized. The molecular structure of complex has been determined by the single crystal X-ray diffraction. The complex has been observed to crystallize in the monoclinic space group P2(1)/c. The asymmetric unit of compound consists of two crystallographically different Ag(I) centers and one pydc ligand. The Ag1 and Ag2 adopt tetrahedral and T-shaped geometries, respectively. At the same time, the silver(I) compound consists of a fish bone similar to the 1D silver cluster. Furthermore, novel coordination mode shown by H(2)pydc indicates that the crystal exhibits photoluminescence in the solid state at room temperature.
