Crystals of 2b were found to contain lattice disordered solvent 
molecules, which could not be sufficiently modeled in the refinement 
cycles. These molecules were removed using the SQUEEZE procedure 
(P., Van der Sluis & A. L. Spek, Acta Crystallogr. A46, 194 (1990)) 
implemented in the PLATON package ( A. L. Spek, Acta Crystallogr. 
A46, C34 (1990)).
