Cross section through the PES for (1) calculated at the B3LYP/6-311++G(d,p) level of theory; θ1 = −90°, θ2 in steps of 10° (see Fig. 2 for the definition of θ1 and θ2). Note the close vicinity between the molecular structure in the crystal (red box) and the theoretical minimum energy structure (black circle). |
