Changing aromatic properties through stacking: the face-to-face dimer of Ni(ii) bis(pentafluorophenyl)norcorrole

Abstract

Nuclear magnetic resonance (NMR) shielding constants have been calculated for Ni(II) bis(pentafluorophenyl)norcorrole and its face-to-face stacked dimer at the Hartree-Fock (HF), second-order Møller-Plesset perturbation theory (MP2), complete-active-space self-consistent-field (CASSCF) levels...
