Displacement ellipsoid representation of (a) felodipine (form IV) (1), (b) nifedipine (α form) (2), (c) nifedipine·1,4-dioxane solvate (2·1,4-dioxane), (d) nisoldipine (3), (e) nitrendipine (4), (f) cilnidipine (5), (g) nimodipine (6) and (h) nimodipine·DMSO solvate (6·DMSO), with atomic displacement parameters drawn at the 50% probability level. Grey: carbon, blue: nitrogen, red: oxygen, green: chlorine and yellow: sulfur. |
