Figure 2
The molecular packing in (I), shown in a perspective view along the a axis. Thick dashed lines represent C=O⋯O and C⋯O closed-shell bonding contacts, while thin dashed lines represent C—H⋯O hydrogen bonds. The dot indicates the inversion center located in the middle of the unit cell. [Symmetry codes: (ii) x − , −y + , −z + ; (iii) x, y, z − 1.] |
