 The Platon SQUEEZE procedure was applied to recover 2859 electrons per
 unit cell in a void (total volume 6282 A^3), that is, 119 electrons
 per formula unit. On the basis of microanalytical data, the void content
 may include 1 protonated dmf molecule as well as 2 dmf molecule,
 i.e., a total of 121 electrons not  far from the values estimated by
 SQUEEZE. Those solvent molecules have  been included in the formula for
 the calculation of intensive  properties, thus justifying the checkcif
 report allerts CHEMW03_ALERT_2_A and DIFF003_ALERT_1_A.
