Abstract:
The structures of gas-phase platinum nitrosyl ion-molecule complexes, [Pt(NO)n]+ (n = 3-7), have been investigated using a combination of infrared photodissociation action spectroscopy and quantum chemical simulations. Nitric oxide binds in a combination of linear and bent motifs associated with nominal three- and one-electron donation, respectively, and there is clear evidence of a first solvation shell closing at six ligands. Oxygen rich complexes are also observed in the mass spectrum and their infrared spectra indicate the formation of an N2O3 moiety. Calculations support the interpretation of [Pt(N2O3)(NO)n]+ complexes arising from exothermic intracluster reactions in which [⋯(NO)3⋯]+ complexes form [⋯(NO2)(N2O)⋯]+ species from which the more weakly-bound nitrous oxide is lost.

02:46Crystal 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,...

02:58Crystal 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...
