A new type of pincer ligand (1) featuring an Sb(I) center and two pendent amine arms has been developed. The single electron oxidation of 1 produces a dicationic distibine (2). Crystallographic and computational investigations indicate that 2 gains stabilization from intramolecular π-π interactions and second-sphere coordination. The reactions of 2 with a disulfide and Co2(CO)8 reveal its dual redox reactivity associated with the oxidation of the Sb-Sb bond and the reduction of the cationic Sb(II) centers.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
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...
Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...
