Abstract
The metal organic frameworks (MOFs) were synthesized by the reaction of the benzene-1,4-dicarboxylic acid (terephtalic acid (TPA)) ligand with the corresponding metal salts such as CrCl3, SbCl3, In-2(SO4)(3), and VCl3 in 1:2 molar ratio. These complexes were characterized by the BET measurement, scanning electron microscopy, thermogravimetric analyzer (TGA), magnetic susceptibility measurements, FT-IR and electronic spectral studies. The thermal stability and the magnetic sussepcibility of the MOFs were also studied by TGA analyses and Gouy method. These studies show that all the MOFs have octahedral arrangement around the metal ions except vanadium cxcomplex which is distorted square pyramidal geometry. Zeta potential of TPA, TPA-Cr, and TPA-Sb MOFs were shown that formulations have neutral, TPA-In and TPA-V MOFs positive and negative surface charges.
