Fig. 1. (a) proptrz = (E)-3-phenyl-N-(4H-1,2,4-triazol-4-yl)prop-2-yn-1-imine. (b) Single crystal structure of two neighbouring layers of 1(Pd)·2H2O at 200 K (viewed in the bc-plane) highlighting host–guest interactions, ligand interdigitation, and the octahedral Fe(ii) coordination environment. (Water guest molecules are shown as large red spheres, metal ions as small spheres, and the rest of the framework as sticks.).
