Tetrakis(dimethyl sulfide)palladium(II) bis(tetrafluoroborate) and tetrakis(1,4‐oxathiane‐κS)palladium(II) bis(tetrafluoroborate)

Tetrakis(dimethyl sulfide)palladium(II) bis(tetrafluoroborate), [Pd(C₂H₆S)₄](BF₄)₂, (I), and tetrakis(1,4‐oxa­thiane‐κS)palladium(II) bis­(tetra­fluoro­borate), [Pd(C₄H₈OS)₄](BF₄)₂, (II), both crystallize as mononuclear square‐planar complexes with tetra­fluoro­borate as the counter‐ions. The Pd atom accepts four S‐donor atoms and is positioned at an inversion centre in both compounds. The two unique S atoms in the di­methyl sulfide complex, (I), are disordered. The Pd—S distances are in the range 2.3338 (12)–2.3375 (12) Å in (I), and the corresponding distances in the thio­xane complex, (II), are 2.3293 (17) and 2.3406 (17) Å. The anions in both compounds interact weakly with the Pd atom.
