Fig. 2. (a) Single crystal structure of 1(Pd)·2H2O at 200 K (viewed in the ac-plane), showing the aromatic interactions between pairs of ligands. (b) Illustration of the likely structure of 1(Pd) (viewed in the ac-plane) obtained from constrained Rietveld refinement of the LS structure at 150 K, which suggests that with guest water removal, optimisation of the ligand–ligand interactions occurs towards 1D chains.
