Monopotassium monosodium hexahydrogen α-hexamolybdoplatinate(IV) undecahydrate

چکیده
The title compound, KNa[H(6)PtMo(6)O(24)]·11H(2)O, contains a discrete hexa-molybdoplatinate(IV) [H(6)PtMo(6)O(24)](2-) poly-anion (1 symmetry), which has the highest level of protonation. Five O atoms of the central PtO(6) octa-hedron (μ(3)-atoms, Oc) and one O atom of an outer edge-sharing MoO(6) octa-hedron (O bridging μ(2)-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 mol-ecules. The two independent K(+) cations are equally disordered about a twofold rotation axis.

Redetermination of heptapotassium nonahydrogen bis[α-hexamolybdoplatinate(IV)] undecahydrate
Previously reported at a temperature of 298 (2) K [Lee & Joo (2007 ▶). Acta Cryst. E63, i11-i13], the title compound, K(7)[H(9)α-Pt(2)Mo(12)O(48)]·11H(2)O or K(7)[H(4.5)α-PtMo(6)O(24)](2)·11H(2)O, was redetermined at 146 (2) K in order to determine whether the H atom in the hydrogen bond that crosses the center of symmetry was located at the center of symmetry or disordered around it as assumed...
متن کاملDouble salt crystal structure of hexasodium hemiundecahydrogen α-hexamolybdoplatinate(IV) heminonahydrogen α-hexamolybdoplatinate(IV) nonacosahydrate: dihydrogen disordered-mixture double salt
The title double salt containing two distinct, differently protonated hexa-molybdoplatinate(IV) polyanions, Na6[H5.5 α-PtMo6O24][H4.5 α-PtMo6O24]·29H2O, has been synthesized by a hydro-thermal reaction at ca pH 1.80. The positions of the H atoms in the polyanions were established from difference Fourier maps and confirmed by the inter-polyanion hydrogen bonds, bond-distance elongation, and bond...
متن کاملQuantification of cation-anion interactions in crystalline monopotassium and monosodium glutamate salts.
Crystalline salt compounds composed of metal cations and organic anions are becoming increasingly popular in a number of fields, including the pharmaceutical and food industries, where such formulations can lead to increased product solubility. The origins of these effects are often in the interactions between the individual components in the crystals, and understanding these forces is paramoun...
متن کاملNephrotoxic effect of MSG (monosodium glutamate) in the chicken.
In order to prove sodium toxicity of MSG, baby chicks known to be the most susceptible one to sodium chloride were chosen as the experimental animal. Almost isotonic solution of MSG, NaCI or monopotassium glutamate was given ad libitum as the sole source of drinking water. Two-day old chickens given MSG died of gout within a few days and showed higher mortality and lesions severer than those gi...
