The knowledge about parameters of C-13 and F-19 NMR spectra of the heptafluoroindenyl cation was expanded here. Quantum-chemical calculations were performed for F-19- and C-13-chemical shifts (CSs) as well as F-19-F-19 and C-13-F-19 spin-spin coupling constants (SSCC5). CSs were predicted by the GIAO/PBE/L22 method. The computation accuracy of CS values increased for the cation in conjunction with the anion SbF6-. The SOPPA method was used to calculate direct C-13-F-19 SSCC5 and their Ramsey contributions. Other C-13-F-19 and F-19-F-19 SSCCs were predicted by the DFT/B3LYP method. The accuracy of these calculations was shown to increase when the anion influence was taken into account. (C) 2017 Elsevier B.V. All rights reserved.
