Fig. 4: 3D/3D systems formed from [Sn12]2− and [Sn10]2−.
From: 3D and 2D aromatic units behave like oil and water in the case of benzocarborane derivatives

Computed NICS (in ppm) at the center of different five- and four-membered rings and at the center of each cluster are enclosed. Sn atoms in gray.
