Two Zn(II)-containing complexes based on fluconazole, {[Zn(HFlu)2(IPA)]·9H2O}n(1), {[Zn(HFlu)2(OH-BDC)]·8H2O}n(2) (HFlu = fluconazole; 2-(2,4-difluoro- phenyl)-1,3-bis(1,2,4-triazol-1-yl)-propan-2-ol; H2IPA = isophthalic acid; OH-H2BDC = 5-hydroxyisophthalic acid) have been synthesized and structurally characterized. Complex1and2are both a one-dimensional (1D) tubular structure with the distorted dinuclear zinc rectangular-shaped cavity, and large free water molecules involved in strong O‒H···O and O‒H···N hydrogen bonds are accommodated in the 1D tubular structure. The thermal stabilities and photoluminescent properties of the coordination polymers have also been investigated. [ABSTRACT FROM AUTHOR]

Two new metal-organic frameworks, namely [Cd(3-NO2-bdc)(2,2′-bpy)(H2O)•H2O]2(1) and[Ni(3-NO2-bdc)(4,4′-bpy)H2O]n(2) (where 3-NO2-bdcH2= 3-nitro-1,2-benzenedicarboxylic acid, 2,2′-bpy = 2,2′-bipyridine, 4,4′-bpy = 4,4′-bipyridine), have been synthesized and structurally characterized. Complex 1 is a 0-dimensional (0D) framework, but face-to-face π-π stacking interactions and O–H···O hydrogen bonds extend these molecules into a 3D supramolecular framework. X-ray structure analysis reveals that complexes 2 exhibit a 2-dimensional (2D) network structure. Also, IR spectra, fluorescence properties, thermal decomposition process, and powder X-ray diffraction of the complexes were investigated. [ABSTRACT FROM PUBLISHER]
