Synthesis and characterisation of palladium(<scp>II</scp>) complexes of mixed thioether/oxa ionophores. Crystal structures of [PdCl<sub>2</sub>([18]aneS<sub>2</sub>O<sub>4</sub>)], [Pd([18]aneS<sub>2</sub>O<sub>4</sub>)<sub>2</sub>][PF<sub>6</sub>]<sub>2</sub>([18]aneS<sub>2</sub>O<sub>4</sub>= 1,4,7,10-tetraoxa-13,16-dithiacyclooctadecane) and [Pd([18]aneS<sub>3</sub>O<sub>3</sub>)<sub>2</sub>][PF<sub>6</sub>]<sub>2</sub>([18]aneS<sub>3</sub>O<sub>3</sub>= 1,4,7-trioxa-10,13,16-trithiacyclooctadecane)

Cl(2)–Pd–S(4) 179.24(4) and S(1)–Pd–S(4) 88.96(4)°. The near-planar macrocycle co-ordinates as a bidentate chelating ligand via the exo oriented S-donor atoms leaving the endo oriented O atoms free. The SCH2CH2S moiety adopts a gauche conformation [S(1)–C(2)–C(3)–S(4)–58.3(4)°] with the ethylene bridge occupying part of the macrocyclic cavity. The crystal structure of [Pd([18]aneS2O4)2][PF6]2 showed
