Figure 5
Representation of the crystal structures of compounds 13, (a) along the crystallographic b axis and (b) in the [[{\overline 1}0{\overline 1}]] direction. The principal axes (X1, X2 and X3) for the thermal expansion are also shown. Chain-like one-dimensional structural motifs formed by ππ interactions (indicated by red circles) of the C=C double bonds of the styryl­pyridine ligands are represented in green and yellow. The inset in (b) highlights the interchain interactions in compound 2.
