The molecule of polymorph (I). Ellipsoids correspond to 30% probability levels. Only the asymmetric unit is numbered. Selected molecular dimensions: C1—O1 1.235 (3), C1—N1 1.3434 (16), N1—C2 1.4394 (19) Å; O1—C1—N1 122.07 (10), N1i—C1—N1 115.87 (19), C1—N1—C2 122.36 (16)°. Symmetry code: (i) 1-x, 1-y, z. Librationally corrected bond lengths (Rlib = 0.014; Schomaker & Trueblood, 1968): C1—O1 1.263, C1—N1 1.358, N1—C2 1.453 Å. |
