Abstract:
The reaction of [(CpPPh(2))(2)ZrCl(2)] (1 a) with two molar equivalents of (Me(2)S)AuCl gave the trimetallic complex [(CpPPh(2)AuCl)(2)ZrCl(2)] (6). Crystalline complex 6 shows a conformational structure that features both P--Au--Cl vectors oriented toward the open front side of the bent metallocene wedge. Quantum-chemical calculations rationalized the absence of an aurophilic AuAu interaction in 6 by showing that a combination of noncovalent forces overcompensates any possible attractive AuAu interaction.

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.
CFT focuses on...
