Abstract:
We report the first noble-gas-stabilized planar tetracoordinate sulfur dications, Ng4S2+ (Ng = Ar, Kr, Xe), as true global minima with remarkable dynamic stability. Bonding analyses reveal predominantly covalent S-Ng interactions driven by ligand-to-center electron donation. In contrast, lighter He and Ne analogues are unstable, mirroring the previously reported Ng4O2+ case.

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 the dxy,...
