The molecule of polymorph (II). Ellipsoids correspond to 50% probability levels. Only the asymmetric unit is numbered. Selected molecular dimensions: C1—O1 1.241 (2), C1—N1 1.3512 (14), N1—C2 1.4474 (17) Å, O1—C1—N1 122.06 (8), N1i—C1—N1 115.87 (15), C1—N1—C2 122.39 (12)°. Symmetry code: (i) 1-x, 1-y, z. Librationally corrected bond lengths (Rlib = 0.027; Schomaker & Trueblood, 1968): C1—O1 1.253, C1—N1 1.357, N1—C2 1.452 Å. |
