The reactions of 1,2-bis(diphenylphosphanyl)ethane (dppe) with different silver(I) salts facilitated the formation of 1D and 2D coordination polymers, [Ag(dppe)(OAc)](n)center dot nH(2)O (1) and [Ag-2(dppe)(1.5)(NO3)(2)](n) (2), respectively. The complexes were characterized by elemental analysis, ATR-IR spectroscopy, H-1 NMR, C-13 NMR, and P-31 NMR spectroscopy, and single-crystal X-ray diffraction. Structural analysis revealed that complex 1 exhibits a 1D infinite wavy structure, in which each silver(I) ion is bridged by dppe ligands. Structure 2 has a 2D topologically promising architecture that displays a 6.6.6 graphitic net, which corresponds to hnd topology. The nitrate ions and dppe ligands are in a mu(2) bridging mode and support the formation of this net. Moreover, significant pi-pi interactions between the phenyl rings in the apertures of (6,3) grid stabilized complex 2.
