and the ECP-based LANL2TZ(f) on the metal centre.61 The C-
PCM implicit solvation model (3 ¼ 9.08) was added to M06
calculations.62 Gaussian ’09 was used as soware.63 All the
stationary points were characterized by IR simulations
(harmonic approximation), from which zero-point vibrational
energies and thermal corrections (T ¼ 298.15 K) were ob-
tained.64 Vibrational simulation supported the interpretation of
experimental IR data. Cartesian coordinates of the optimized
geometries are collected in a separated. xyz le.
