Figure 2 Part of the crystal packing of the title compound, viewed along the a axis, showing the formation of a molecular trimer. Atom-numbering is shown for those non-H atoms involved in hydrogen bonds and intermolecular interactions are shown as dashed lines. Molecule A is is related to molecules B and C via symmetry codes of −x + , −y + , −z and −x + , y + , −z + , respectively. |
