Syntheses, crystal structures and luminescent properties of Ag(I) complexes with benzilic carboxylate and 2,6-pyridinedicarboxylate

ABSTRACTTwo complexes [Ag(bpy)(H2O)]·(Hbac) (1) and [Ag2(bpy)2(H2O)2](pdc)·(H2O)5 (2) (H2bac = benzilic acid, bpy = 4,4′-bypyridine, H2pdc = 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, a = 18.8192(5) A, b = 12.7131(5) A, c = 17.8373(8) A, β = 95.745(4)°, V = 4246.1(3) A3 and Z = 8; 2: Triclinic, space group, P-1, a = 8.132(5) A, b = 10.485(6) A, c = 18.026(10) A, α = 96.194(10)°, β = 91.047(11)°, γ = 105.866(10)°, V = 1468.0(15) A3 and Z = 2. In complex 1, Ag(I) is coordinated by two discrete 4,4′-bpy ligands and one water molecule and Hbac− behaves as a counterpart anion. In the crystal, a 3D network was formed by hydrogen bonds and π–π face-to-face interactions. In complex 2, Ag(I) is also coordinated by two discrete 4,4′-bpy ligands and one water molecule and pdc2− behaves as a counterpart anion, too. In the crystal, a similar 3D network was formed by hydrogen ...
