 On the basis of the solvents used, and by analogy with the structure of
 the isomorphous Cd analogue (RD1109b), both the coordinated and included
 solvents were assumed to be dmf (C3H7NO) = 40e.
 Due to severe disorder, only the oxygen atom of the coordinated solvent
 molecule could be reliably located.
 So, at the time of running SQUEEZE, the asu contents were low by
 (C3H7N). However, SQUEEZE does not remove electron density that is
 within bonding distance of defined atoms, so the contribution of the
 carbonyl carbon would not be removed, meaning that (C2H7N) = 26 e/asu
 of that removed by SQUEEZE would be due to the coordinated solvent.
 
 SQUEEZE suggested 29377 e/cell = 306 e/asu.
 As detailed above, the disorder of the coordinated solvent accounts for
 26 e/asu of this, leaving 280 e/asu for the included solvent.
 The included solvent is presumed to be dmf (C3H7NO) = 40e.
 7dmf = 280e so this was used as the solvent present.
 7dmf per asu = 28dmf per LMn2 unit.

 So, atom list low by (C3H7N) + 7(C3H7NO) = C24 H56 N8 O7,
 and UNIT low by C2304 H5376 N768 O672,
 i.e. C672 H384 N384 O96 Si24 Mn48
