Abstract:
We present the results of a density functional calculation on adsorption of O(2), CO, and their coadsorption at various sites of neutral, cationic, and anionic Pd(4) clusters. For all the clusters, the dissociative adsorption of oxygen sitting on Pd bridge sites is found to be preferable. Both O(2) and CO binding energies are found to be higher for the anionic Pd(4) cluster followed by cationic and neutral cluster. However, binding energies of O(2) or CO in the coadsorption complexes follow the trend: anionic > neutral > cationic.

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.
