Sažetak
The title compound has been synthesized under solvothermal conditions by reacting vanadium(V) oxytriisopropoxide with terephthalic acid in N, N-dimethylformamide. A combination of synchrotron powder diffraction, infrared spectroscopy, scanning and transmission electron microscopy, thermal and chemical analysis elucidated the chemical, structural and microstructural features of new 2D layered inorganic-organic framework. Due to the low-crystallinity of the final material, its crystal structure has been solved from synchrotron X-ray powder diffraction data using a direct space global optimization technique and subsequent constraint Rietveld refinement. [V4O4(OH)2(O2CC6H4CO2)•DMF] crystallizes in the monoclinic system (space group P2/m (No. 10)) ; cell parameters: a = 20.923(4), b = 5.963(4), c = 20.425(3) Å,  = 123.701(6) º, V = 2120.1(15) Å3, Z = 2, DC = 1.613(1) g/cm3. The overall structure can be described as an array of parallel 2D layers running along [-101] direction, consisting of two types of vanadium oxidation states and coordination polyhedra: face-shared trigonal prisms (V4+) and distorted corner-shared square pyramids (V5+). Both configurations form independent parallel chains oriented along the 2-fold symmetry crystallographic b-axis mutually interlinked with terephthalate ligands in a monodentate mode perpendicular to it. The structural cohesion has been achieved by interlayer CH···O hydrogen bonding via N, N-dimethylformamide molecule. The morphology of the compound exhibits long nanofibers, with the growth direction along the layered [-101] axis. The magnetic susceptibility measurements show that the magnetic properties of V4O4(OH)2(O2CC6H4CO2)•DMF can be described by a linear antiferromagnetic chain model, with the isotropic exchange interaction of J = −75 K between the nearest V4+ neighbours of S = 1/2.
