Figure 3 Packing view of (1) projected down a, showing on the projection plane (running vertically, in hollow bonds) the 'solvato' chains. Perpendicular to the latter and coming out of the plane (in bold, full bonds) the 'dimeric' chains. Intra- as well as inter-chain H-bonds shown in broken lines. For clarity, only the carboxylato end of the butenoate units have been drawn. Symmetry codes: (i) −x, −y, −z; (ii) x, y + 1, z; (iii) −x + 1, −y + 2, −z + 1; (iv) −x + 1, −y + 1, −z + 1; (v) −x + 1, −y, −z; (vi) −x + 1, −y + 1, −z; (vii) x − 1, y − 1, z. |
