Figure 11
Dimer hydrogen-bonding motif seen in 3, linked via the chiral C4 centre. Dimers are linked via methoxy–ketone hydrogen bonding, forming a ribbon that extends parallel to the c axis. Only hydrogen atoms involved in intra- and intermolecular hydrogen bonding are shown. Dotted lines indicate hydrogen-bonding interactions. [Symmetry codes: (i) −x + 1, −y + 2, −z + 1; (ii) −x + 1, −y + 2, −z]. |
