Abstract
Three new complexes [Cd(Hflu)2(NO3)](NO3) 1, [Cd(H2O)(Hflu)2(Hmalo)](NO3)×2(H2O) 2, and [Cd(H2O)(Hflu)2(Hfum)](NO3)×2(H2O) 3 (Hflu = [2-(2,4-difluorophenyl)-1,3-bis(1,2,4-triazol-1-yl)-propan-2-ol], H2fum = fumaric acid, H2malo = malonate acid) are synthesized by a solution diffusion method and characterized by single crystal X-ray diffraction methods, elemental analyses, IR spectroscopy as well as thermal analyses. In compound 1, Cd(II) cations are bridged by fluconazole ligands to form 2D Cd-Hflu layers, and these layers are further connected by C-H⋯F hydrogen bonds to form a complicated 3D structure with the topology of (4×6×8)(4×64×84×10)(6×3). Compounds 2 and 3 are isostructural, and in them the Cd(II) cations are bridged by fluconazole ligands to form a 2D network, which is connected by C-H⋯O hydrogen bonds to form a complicated 3D (3,4)-connected framework with the topology of (4×82)(4×85).
