    • 1 value because of the extremely weak diffraction of the sample, though the crystal was not small. Diffraction data have been measured up to 20.06°, but this prevented us from collecting enough reflections for an acceptable refinement of the structure. However, the connectivity is clear, and the disordered solvent (an important part of the structure) is well defined. CCDC-671424 contains the supplementary crystallographic data for this paper.
