Abstract:
The electronic and molecular structures of selected zerovalent d and f metal bis-eta6-benzene sandwich complexes M(C6H6)2 (M = Sc, Ti, V, Cr, Y, Zr, Nb, Mo, La, Ce, Gd, Lu, Hf, Ta, Nb, Th) were investigated at the scalar-relativistic level using a combination of energy-consistent ab initio pseudopotentials and gradient-corrected density functionals. The results are compared to previous pseudopotential coupled-cluster and all-electron density functional results based on the zero-order regular approximate Hamiltonian of Chang, Pelissier, and Durand as well as to experimental data.

Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the number...
