Although the density for the chloro-benzene group is quite strong, the density for the benzisoxazole group becomes weak (approximately half of the group, closest to the chloro-benzene, is well resolved). Finally, density for the morpholine group is very weak, and likely indicates significant mobility of this group. (B) Density for the terminal morpoline group resolved only after a run with autoBuster (with the ligand omited from the structure). A futher run with the ligand roughly positioned but omited from the calculations (-Lpdb) provided the density used to refine the position of the ligand. However, the refined group B-factors for the ligand (~53) indicate that the ligand is highly mobile, and the modeled configuration is likely not the sole conformation of the tail of the compound
