Two complexes [Ag(bpy)(H2O)](Hbac) (1) and [Ag-2(bpy)(2)(H2O)(2)](pdc)(H2O)(5) (2) (H(2)bac = benzilic acid, bpy = 4,4 '-bypyridine, H(2)pdc = 2,6-pyridinedicarboxylic acid) have been synthesized and characterized by IR, element analysis, X-ray-single crystal diffraction and TGA. Crystal data for 1: Monoclinic, space group C2/c, alpha = 18.8192(5) a, b = 12.7131(5) a, c = 17.8373(8) a, beta = 95.745(4), V = 4246.1(3) a(3) and Z = 8; 2: Triclinic, space group, P-1, alpha = 8.132(5) a, b = 10.485(6) a, c = 18.026(10) a, alpha = 96.194(10), beta = 91.047(11), gamma = 105.866(10), V = 1468.0(15) a...
