摘要：In this study, we investigated the crystal structure, optical, thermal, dielectric and magnetic properties ofcation deficient potassium tris(oxalato)ferrate(III) trihydrate {K2.72[Fe(C2O4)3]·3.17H2O} crystals. Single crystal X-rayanalysis reveals that the compound crystallized in the monoclinic system with P21/c space group and exhibits a threedimensional(3D) chain structure. The structure of the complex consists of infinite anionic [Fe(C2O4)3]3- units withFe(III) metal center possesses a distorted octahedral environment surrounded by six oxygen atoms from three bidentateoxalate ligands. Raman spectroscopy was used to study the vibrational modes of the compound. The two broadabsorption bands at 676 and 972 nm from UV–vis absorbance spectra were attributed to a ligand to-metal chargetransfer. The thermal studies of the compound confirm the presence of water molecule. The magnetic susceptibility andfield dependent magnetization measurements revealed a paramagnetic behavior above 2.5 K and antiferromagneticordering at low temperatures.
