  1. The entries are ordered in terms of increasing d(In−In) values. Supplementary Table 15 contains a comprehensive compilation.
  2. *The very short In−In bond lengths (258.1 and 259.7 pm) correspond to the bridging In1−In3 distances within the rhombic 64+ and 74+.
  3. The references are included with Supplementary Table 15.
