;
The disordered solvents within the void were not crystallographically
well defined.
The SQUEEZE routine of the program PLATON was used
in order to eliminate the contribution of disordered solvents molecules,
thereby a final model based only on the ordered part of the crystal structure
was obtained.
The SQUEEZE routine suggested that a total potential solvent area volume
of 2238.8 Ang^3^, and a void electron population of 387 per cell.
Because the solvent involved in the recrystallization is toluene,
the amount of the disordered solvent was 8 per cell suggested by electron count.
The overall formula should be (C128H156Lu2N12O6).2(C7H8), considering the
contribution of solvent.
