Figure 3
Structure A of 3Se with the chalcogen bonding, hydrogen bonding and anion–π interactions marked, and with displacement ellipsoids drawn at the 50% probability level. For the sake of clarity, only H atoms involved in hydrogen bonding are shown. Symmetry operation to generate the second molecule of 3Se and trifluoromethanesulfonate: −x + 1, −y + 1, −x + 1. |
