Four new fluconazole-bridged zinc(II) and cadmium(II) complexes with dicarboxylate co-ligands, namely [Zn(HFlu)(TPA)]n (1), {[Cd(HFlu)2(TPA)]·2CH3OH}n (2), [Zn(HFlu)2(Suc)(H2O)2]·H2O (3), and [Cd(HFlu)2(Suc)(H2O)2]·H2O (4), have been synthesized and characterized by elemental analysis, IR, TG, and single-crystal X-ray diffraction (HFlu = 2-(2,4-difluorophenyl)-1,3-bis(1,2,4-triazol-1-yl)-propan-2-ol, H2TPA = terephthalic acid, and H2Suc = succinic acid). Complex 1 displays a 2-D corrugated network with common (4,4) topology, in which two types of grids constructed by two bridging TPA dianions and two HFlu ligands are found. Complex 2 shows an unusual (3,6) coordination layer consisting of alternative PMPM Cd–HFlu helical chains in which the Cd(II) nodes are also fixed by terephthalate dianions in a cis fashion. The isostructural complexes 3 and 4 have 20-membered dimeric macrocyclic motifs with the Zn···Zn and Cd···Cd distances of 11.258(2) and 11.528(2) Å, respectively. The fluorescence and thermal stability of complexes 1–4 have also been investigated.
Four new complexes with fluconazole have been prepared by introducing dicarboxylate co-ligands. Terephthalic acid induces to generate a 2-D corrugated network with common (4,4) topology in 1 and an unusual (3,6) layer with alternative Cd–HFlu helical chains in 2. Succinic induces to generate two isostructural dinuclear units in 3 and 4. The fluorescence and thermal stability have also been investigated.Figure optionsDownload as PowerPoint slide
