13. We suggest the use of the symbol ⊙ to indicate an incarcerated complex and the symbol for the nesting complex found in the caviplexes. These are modifications of a dot alone between two molecules, which has been used to indicate crystalline interstitial solvates. Sometimes all three of these phenomena are found in a single crystalline complex and require differentiation.
