Abstract
In this study, we investigated the crystal structure, ultraviolet (UV) luminescence, and magnetic properties of potassium bis oxalate nickel(II) tetrahydrate {K2[Ni(C2O4)2(H2O)2]·4H2O} crystals. This compound crystallizes in the monoclinic system with a P21/c space group and exhibits a one-dimensional (1D) chain structure. The Ni(II) metal center possesses an octahedral environment, with four oxygen atoms from two bidentate oxalate ligands and two oxygen atoms from water molecules. Infrared spectroscopy was used to study the vibrational modes of the compound. Interestingly, the complex exhibits intense UV emission at 364nm when excited at 323nm. Furthermore, the luminescence lifetime is approximately 50µs. The magnetic susceptibility and field dependent magnetization measurements revealed a paramagnetic behavior above 20K and antiferromagnetic ordering at low temperatures.
