Figure 1
View of the dication in (I), showing the atom-numbering scheme adopted. Displacement ellipsoids are drawn at the 50% probability level. Intramolecular C—H⋯I hydrogen bonds: C6⋯I = 3.779 (11), H6A⋯I = 2.84, C5i⋯I = 3.755 (10), H5A⋯I = 2.80 Å, C6—H6A⋯I = 162 and C5—H5A⋯Ii = 161°. [Symmetry code: (i) −x + , −y + , −z + 1.] |
