Synthesis, Crystal Structure and Luminescence of a One-Dimensional Chain-Like Complex [Ag(L)]•H2O

The title compound, [Ag(L)center dot H2O, 1, where HL=4-(isonicotinamido)benzoic acid, was synthesized in methanol solution and its crystal structure was determined by X-ray diffraction analysis. The crystal is of monoclinic, space group P2(1)/c with a=0.571 8(8) nm, b=1.357 2(18) nm, c=1.558 0(2) nm, beta=91.090(2)degrees, V=1.209 0(3) nm(3), Z=4, D-c=2.009 g center dot cm(-3), F(000)=722, R-int=0.042 9, R=0.027 1, wR=0.055 6. In complex 1, the Ag atoms are linearly coordinated by one O atom and one N atom of two ligand molecules. Each L ligand in turn uses its one carboxylate group and one pyridinyl groups to connect two metal centers, then the one-dimensional (1D) chains is formed. On the other hand, the 1D chains are further connected by O1W-H1WB center dot center dot center dot O2 hydrogen bonds and Ag-O weak interactions to give a two-dimensional (2D) layer, finally, the 2D net extents to three-dimensional (3D) supramolecular framework by OIW-H1WB center dot center dot center dot OI as well as N-2-H-2 center dot center dot center dot O-2 interactions.
