Fig. 1: X-ray crystal structure of Pd1Au1@1.

a,b, Formation of Pd1–Au1 dimers showing the structures of 1 (a) and Pd1Au1@1 (b) determined by SCXRD. c,d, A single channel of Pd1Au1@1 in the ab (c) and bc (d) plane. Copper and strontium atoms from the network are represented by cyan and purple polyedra, respectively, in a,b, whereas they are represented by grey sticks in c,d. Organic ligands are depicted as grey sticks and thioether groups as yellow sticks in all cases. Orange and blue spheres represent gold and palladium atoms, respectively, in Pd1–Au1 dimers. Blue, orange and red dotted lines represent the Pd⋯S, Au⋯S and Au⋯O interactions, respectively. e, Details of X-ray crystal structure showing the main host–guest interactions and related structural parameters of Pd1–Au1 dimers.
