All new calculated conformers and isomers at CCSD(T)-F12/cc-pCVTZ-F12 level. Conformers of the same isomer are grouped in the same box. Each box is colour-coded according to the minimum energy of the relative conformer. From the most to the least favourable isomer, normalised colour scale ranges from violet to yellow, respectively. The SP and TS are both highlighted by lighter-coloured boxes. The average value of the isomer’s conformers, which does not include TS and SP, and the values of each conformer are reported with a grey dotted line and a black solid line, respectively. The numerical value of the latter is also given.
