Figure 2
The molecular structure of (I) and the hydrogen-bond interactions (not including the `weak' hydrogen bonds). Displacement ellipsoids are drawn at the 50% probability level. Symmetry operations (in the text and all figures): (i) 2 + x, − y, z − ; (ii) x + 1, − y, − z; (iii) −x − 1, 1 − y, 1 − z; (iv) x − 1, − y, + z; (v) x − 2, − y, + z; (vi) x + 1, y, z; (vii) −x, 1 − y, 1 − z; (viii) x − 1, y, z. |
