The crystal structure of the complex Li-3[Fe(C2O4)(3)]. 5H(2)O has been determined by X-ray diffraction analysis. The coordination of the iron atom is a distorted octahedron composed of the oxygen atoms of three oxalate ions. Two of the lithium ions are octrahedral and the third one is tetrahedral. Infinite chains appear along the b-axis, with alternation of Fe3+ and Li+ cations separated by oxalate anions. In agreement with this, the Mossbauer spectrum consists of an asymmetric and strongly broadened absorption pattern, indicating the presence of both paramagnetic relaxation effects and quadrupolar interaction which result from an Fe3+ interionic shortest distance of 6.559 Angstrom and from a non-cubic iron environment, respectively.
