The crystal under investigation was diffracting only weakly due to partial lost
of solvent. The solvent/anion system was heavily disordered and could not be
resolved unambiguously. Therefore, the contribution of the missing
molecules and anions to the calculated structure factors was taken into account
with the BYPASS algorithm (van der Sluis & Spek, 1990), implemented as the
SQUEEZE option in PLATON (Spek, 2003). The missing molecules and anions were
not taken into account in unit cell content.
