Bonding Character in the Laves-Phases TiCr2 and TiCo2
The bonding character of Laves phases TiCr2 and TiCo2 has been investigated by electron energy loss spectroscopy and ab-initio calculations. The results revealed the hybridization between the transition-metal atoms in Laves phases. The stronger Cr-Cr (Co-Co) bonding along the Kagome net forms a tetrahedral electronic network in the C15 TiCr2 (TiCo2) structure. This was discussed with the mechanical properties of Laves phases.
