_cell.formula_units_Z_prime_details

Definition:

   
    An account of the assigned value of Z', the number of molecules in
    the asymmetric unit, where there is difficulty in deciding the
    appropriate value for reasons of symmetry, chirality, disorder etc.

;
         Z' has been assigned the value 1 as the catenane is
         considered a single complex of two interlocked molecules
         that cannot be chemically separated, in preference to a
         crystallographic interpretation that considers it as two
         interlinked independent molecules that would suggest
         setting Z' = 2.
