Two silver ammine complexes with the polyprotic aromatic acids benzene-1,2-dicarboxylic acid (phthalic acid) and benzene-1,3,5-tricarboxylic acid (trimesic acid) have been prepared and their stuctures determined using single-crystal X-ray diffraction and infrared spectroscopy.Complex 1, a hydrogen-bonded polymer based on a simple diamminephthalatodisilver(I) species, with an ammonia molecule and a single phthalate carboxylate oxygen bonded to separate silver atoms, giving essentially linear co-ordination a chain polymer.Complex 2, a two-dimensional sheet polymer based on a pseudo-centrosymmetric S-type trimer unit, linked by the carboxylate groups of two independent trimesate residues A third compound 3, ammonium silver(I) pyrazine-2,3-dicarboxylate a procedure similar to that for 1 and 2.However, unlike them, it has no bonded ammines but has a distorted trigonal-planar co-ordination involving two carboxylate oxygens a polymer structure.
