The reaction between freshly precipitated silver oxide Ag2O and an aqueous solution of tetrabenzenecarboxylic acid H4L leads to the anhydrous Ag2H2L complex. It crystallizes in the space groupP21/c, witha=6.457(1),b=8.180(1),c=9.982(1) Å, β=97.83(1)°,V=522.3(1) Å3,Z=2,d=2.976 g cm−3. This structure is a three dimensional polymeric network polymer without any silver...silver interaction. The silver environment is a bipyramid trigonal polyhedron with three short bond distances in the equatorial plane (Ag−O=2.255(2), 2.295(2), and 2.499(2) Å) and two longer bond distances in axial positions (Ag−O=2.558(2) and 2.617(2) Å). Thus, the silver polyhedron involves five different ligands. It is noteworthy that the (H2L2)2− ligand is located around an inversion centre.
