The structure was determined by direct methods. 2842 reflections were collected with single-crystal neutron-diffraction techniques and yielded 1217 independent reflections upon averaging; these were refined to an agreement factor of R(Fo2)=0.056 for all observed data and R(F<sub>O</sub><sup>2</sup>)= 0.053 for 999 data with F<sub>O</sub><sup>2</sup> > lσ (F<sub>O</sub><sup>2</sup>). The structure consists of octahedrally coordinated Pt<sup>IV</sup> metal atoms, one Ba<sup>2+</sup> ion, and two H<sub>2</sub>O molecules (one O and five H atoms are in crystallographic disorder). The Ba<sup>2+</sup> ion is highly coordinated with nine nearest neighbors.Pages 3249-3251application/pdfenPublic Domain (U.S.)Structural studies of precursor and partially oxidized conducting complexes.
