Attempts to refine peaks of residual electron density as guest
atoms were unsuccessful. The data were corrected for disordered
electron density through use of the SQUEEZE procedure (Sluis, P. van der;
Spek, A. L. Acta Crystallogr. 1990, A46, 194-201) as implemented in PLATON
(Spek, A.L. Acta Crystallogr. 1990, A46, C34. PLATON - a multipurpose
crystallographic tool. Utrecht University, Utrecht, The Netherlands).
A total solvent-accessible void volume of 324.1 A^3^ with a totalm ectron count of 31 (consistent with 0.3 molecules of
water per formula) was found in the unit cell.
