A novel silver(I) complex with mixed 2-amino-4-methylpyrimidine (mapym) and naphthalene-2,6-dicarboxylic acid (H(2)npd), {[Ag(mapym)(npd)(0.5)center dot H(2)O]}(n) (1), has been synthesized and characterized by elemental analysis, IR spectroscopy and single crystal X-ray diffraction. In 1, Ag(I) ions exhibit a T-shaped coordination geometry and are doubly clamped by two npd anions to form [Ag(2)C(2)O(4)] units incorporating a short Ag center dot center dot center dot Ag contact of 2.8192(15) angstrom. The coordination bonds link Ag(I) ions and npd ligands to form one-dimensional (1D) fish-bone chains which are extended into a two-dimensional (2D) layer by inter-chain hydrogen bonds. Interestingly, Ag center dot center dot center dot C(npd)(eta(2)) interactions of av. 2.88 angstrom combine inter-layer hydrogen bonds and pi center dot center dot center dot pi stacking interactions to give 1 a three-dimensional (3D) supramolecular framework. The photoluminescence properties of 1 were investigated in the solid state at room temperature.
