Abstract

The syntheses of the palladium(II) complex anions K4Na2[Pd{IO5(OH)}(2)] (.) 8H(2)O and Na-2[Pd{TeO2(OH)(4)}(2)] (.) 5H(2)O are reported. The complexes have been characterised by IR, UV-Vis and NMR spectroscopy. The crystal structure of K4Na2[Pd(IO5(OH)}(2)] (.) 8H(2)O reveals a square planar palladium centre coordinated to two bidentate IO5(OH) groups. The structure of the Pd(IV) complex anion Na-10[Pd-2(IO6)(2){IO5(OH)}(2)] (.) 20H(2)O reveals a new structure type for heteropolyperiodates consisting of six edge-linked octahedra composed of two central IO6 groups coordinated to six-coordinate Pd(IV) with two terminal bidentate IO5(OH) units. Attempts to prepare platinum(II) tellurates or periodates have been unsuccessful, the analogous reactions to those used to prepare Pd(II) complexes leading to the known Pt(IV) complexes.
