- Description
- The first example of a heteropolyoxomolybdate containing palladium(IV) was isolated and characterized by X-ray crystallography. The palladium(IV) hexamolybdate, K₀.₇₅Na₃.₇₅[PdMo₆O₂₄H₃.₅]·17H₂O, was isolated from an aqueous solution at pH 4.5 in the space groupPī,a10.790(2),b12.244(3),c14.086(3) Å,α113.77(1),β90.41(1), γ 107.86(1)°, and the structure was determined using X-ray diffraction methods, refining to a residual of 0.0301 for 5334 reflections. A formal“[PdMo₆O₂₄H₃]⁵⁻” subunit exhibits the basic Anderson structure, with two [PdMo₆O₂₄H₃]⁵⁻ cluster anions in the structure bridged by a hydrogen atom (formally an H⁺) situated on a center of symmetry to give a “[Pd₂Mo₁₂O₄₈H₇]⁹⁻” dimeric anion. The palladium(IV) atom occupies a slightly distorted octahedral environment, with Pd–O distances ranging from 1.968 to 2.009 Å.
