Figure 2
Chair conformation of the molecule (H atoms are omitted for clarity); note the cyclohexane-like conformation at the `carbon-atom side' [folding angle 53.07 (15)° as compared to 54.5 (6)° in the ordered, monoclinic phase of C₆H₁₂ (Kahn et al., 1973

)] and the `semi-flattened' conformation [folding angle 27.96 (7)°] at the `phosphorus/nitrogen-atom side'.
