Crystals of CeFeSb3 were synthesised using a Bi-flux. The compound crystallises in the CePdSb3 structure type and contains alternating slabs of Fe-centered Sb octahedra pairs and Sb square layers separated by layers of Ce atoms. Short Fe-Fe distances of 2.682 Å in the octahedra pairs suggest a covalent bond, which was confirmed by quantum chemical calculations. Magnetisation measurements indicate a complex antiferromagnetic ordering at TN = 4.7 K, attributed to localised Ce 4f moments, likely mediated by RKKY interactions. Mößbauer spectroscopy confirms the non-magnetic behaviour of the Fe atoms. Electrical transport data corroborate CeFeSb3 as a metal with Kondo-like interactions competing with the magnetic ordering.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
