The title compound, KNa[H₆PtMo₆O₂₄]·11H₂O, contains a discrete hexamolybdoplatinate(IV) [H₆PtMo₆O₂₄]²⁻ polyanion (1 symmetry), which has the highest level of protonation. Five O atoms of the central PtO₆ octahedron (μ₃-atoms, Oc) and one O atom of an outer edge-sharing MoO₆ octahedron (O bridging μ₂-atom, Ob) are protonated. The polyanions are connected by almost linear O—H⋯O hydrogen bonds between protonated and unprotonated Ob atoms. Further consolidation of the crystal structure is accomplished by extensive O—H⋯O hydrogen bonding involving the uncoordinated water molecules. The two independent K⁺ cations are equally disordered about a twofold rotation axis.

In our previous studies we isolated the same polyanion, [H₆PtMo₆O₂₄]^2-, that is present in the title compound, (I), at various pH conditions; 1.60 (II; Lee & Joo, 2006b), 0.70 (III; Lee & Sasaki, 1994) and 0.48 (IV; Lee & Joo, 2006a). Structures (II, III) have the same space group, viz. C2/c, whereas the space group of (IV) is P1. The polyanions bear an inversion center in these three structures. The current study was carried out to confirm the presence of a highly protonated species that exists at very low pH.

The structure of the present crystals contains a crystallographically discrete [H₆PMo₆O₂₄]^2- polyanion (Fig. 1). All atoms in the polyanion are located in general positions and consequently the symmetry of the polyanion is C1. The O atoms of the polyoxometalate were designated as Ot (terminal Mo═O atom), Ob (O bridging µ₂-O atom), and Oc (µ₃-O atom). The protonated O atoms in the polyanion were identified in difference Fourier maps and by using structural features as observed in the previously determined structures II & IV, viz. bond lengths of Mo–Oc(H) & Mo–Ob(H) units, bond angles of Mo–Oc(H)–Mo & Mo–Ob(H)–Mo units, and distances between Mo···Mo. As a result, the structure of (I) confirms the protonation of atoms O1c(H), O3c(H), O4c(H), O5c(H), O6c(H) and O8b(H).

The different bond-lengths and bond-angles in the [H₆PtMo₆O₂₄]^2- polyanion of protonated and unprotonated O atoms are compared in Table 1. The protonated O atoms of [H₆PtMo₆O₂₄]^2- in the structures (II), (III) and (IV) show the same protonation scheme, viz. four Oc(H) and two Ob(H) atoms are protonated. Therefore, the feature of the three-dimensional hydrogen bonding formation is very similar in the these polyanions, viz. the central PtO₂(OH)₄ polyhedron forms hydrogen bonds with neighbouring polyanions by four sets of Oc(H)···Ot and Ob(H)···Ot hydrogen bonds.

However, the protonation scheme of the polyanion in (I) is different, consisting of five Oc(H) and one Ob(H) protonated O atoms (Fig. 1). In contrast to the hydrogen bonding scheme in (II-IV), the protonated Oc atoms form various O–H···O hydrogen bonds with water molecules (Ow). Nevertheless, the polyanion is linearly connected by an O8b–H8···O11bⁱ hydrogen bond (Fig.2 and Table 2).

The Na and K ions are coordinated by O atoms as [Na(Ow)₅(Ot)]⁺ in the range 2.371 (7)-2.510 (9) Å, and [K1(Ot)₄(Ow)₂]⁺ and [K2(Ot)₃(Ow)₄]⁺ in the range 2.59 (1)-3.41 (1) Å. Bond valence sum calculations (BVS; Brown & Altermatt, 1985; Brese & O'Keeffe, 1991) for the K1 and K2 ions reveal a considerable undersaturation in terms of valence units which we ascribe to the disordered character of the metal positions.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
