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 topology of (468)(4648410)(63). <...> 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 (482)(485). <...> As compared to coordination polymers with rigid ligands limiting the structures of possible products, researches focusing on those with flexible ligands have currently been undergoing an unprecedented development for their flexible nature which could not only generate the aesthetic beauty of frameworks (such as helix, borromean ring, and torus ring, etc.) [ 7—9], but be also beneficial for the controllable assembly of functional materials such as hybrid magnets [10—12 ] and porous frameworks [ 13, 14 ]. <...> Among the flexible bridging ligands, a variety of h,-dicarboxylic acids and flexible heterocyclic ligand such as various 1,2-bis(4-pyridyl)-ethane and 1,3-bis(4-pyridyl)-propane have been widely employed [ 15, 16 ]. <...> Out of the flexible ligands, the utilization of organic drug [2-(2,4-difluorophenyl)-1,3-bis(1,2,4-triazol-1-yl)-propan-2-ol] (Hflu) molecules as building blocks in crystal engineering of coordination polymers remains largely unexplored [ 17 ]. <...> Three carbon atoms bridge the two triazole ligands and the flexible C—C chain of fluconazole can be rotated for a suitable position and angle to fit the size and geometrical configuration of anions in the self-assembly of metal complexes. <...> Apart from these, weak interactions from Hflu (hydrogen bonding) are also significant to stabilize the structure and/or to form high dimensional structures [18—20 ]. <...> Powder X-ray diffraction measurements were carried out with a Bruker D8 Focus X-ray diffractometer using CuKh radiation with a wavelength of 1.54012 Е at a scan speed of 10 /min to check the phase purity. <...> Single crystal X-ray diffraction data were collected using a Rigaku R-Axis Rapid X-ray diffractometer. <...> Measured and simulated XRD <...>
