Figure 1
The two crystallographically independent supermolecules, with the atomic numbering. Displacement ellipsoids are drawn at the 30% probability level. Conventional hydrogen bonds are shown in heavy dashes and the H⋯O distances span 1.78 (4)–1.96 (4) Å (see Table 1). The C—H⋯O hydrogen bonds (shown as open dashes) are quite weak for this type of interaction (2.73 and 2.72 Å). |
