_platon_squeeze_details
;
Some residual electron density were difficult to modelize and therefore, the
SQUEEZE function of PLATON (Spek, 2003) was used to eliminate the contribution
of the electron density in the solvent region from the intensity data, and the
solvent-free model was employed for the final refinement.

There are two cavities of 136 \%A^3^ per unitl cell. PLATON estimated that
each cavity contains 19 electrons which may correspond to one acetone molecule
(CH~3~)~2~CO by unit cell, as suggested by the crystallization process.
