Synthesis of water and molecular oxygen highly enriched in 17O and 18O isotopes from carbon oxides

The reaction of carbon oxides and hydrogen in the presence of the Raney nickel catalyst has been used for water synthesis. A procedure has been developed for the recovery and collection of the synthesized water with minimal losses and without deteriorating the 17O or 18O isotope enrichment as compared to the initial CO2 and CO. The recovery of oxygen with high concentrations of 17O and 18O isotopes is based on the reaction of xenon difluoride with water. The yield based on oxygen achieves 99% without reduction of isotope enrichment, which is confirmed by mass-spectral measurements of oxygen isotope concentrations in the initial reagents and final reaction products.

Synthesis, raman spectra and crystal structures of [Cu(XeF 2)n](SbF6)2 (n = 2, 4)

Pure [Cu(XeF2)2](SbF6)2 was prepared by the reaction of Cu(SbF6)2 with a stoichiometric amount of XeF2 in anhydrous hydrogen fluoride (aHF) at ambient temperature. The reaction between Cu(SbF6)2 and XeF2 (1:4 molar ratio) in aHF yielded [Cu(XeF2) 4](SbF6)2 contaminated with traces of Xe 2F3SbF6 and CuF2. The 6-fold coordination of Cu2+ in [Cu(XeF2)2](SbF 6)2 includes two fluorine atoms from two XeF2 ligands and four fluorine atoms provided by four [SbF6]- anions. The neighboring [Cu(XeF2)2]2+ moieties are connected via two [SbF6] units, with the bridging fluorine atoms in cis positions, into infinite -[Cu(η1-XeF2) 2]-(cis-η2-SbF6)2- [Cu(η1-XeF2)2]- chains. Because of the high electron affinity of Cu2+, coordinated XeF2 shows the highest distortion (Xe-Fb = 210.2(5) pm, Xe-Ft = 190.6(5) pm) observed so far among all known [Mx+(XeF2) n](A)x (A = BF4, PF6, etc.) complexes. The four equatorial coordination sites of the Cu2+ ion in [Cu(XeF2)4](SbF6)2 are occupied by four XeF2 ligands. Two fluorine atoms belonging to two [SbF 6] units complete the Cu2+ coordination environment. The neighboring [Cu(XeF2)4]2+ species are linked via one [SbF6] unit, with bridging fluorine atoms in trans positions, into linear infinite -[Cu(η1-XeF2) 4]-(trans-η2-SbF6)-[Cu(η1- XeF2)4]- chains. To compensate for the remaining positive charge, crystallographically independent [SbF6]- anions are located between the chains and are fixed in the crystal space by weak Xe...F(Sb) interactions.

New Coordination Compounds of Cd(AsF6)2 with HF and XeF2

Two new coordination compounds of cadmium with HF and XeF2 as ligands have been synthesized. Solid white [Cd(HF)](AsF6) 2 is obtained from an anhydrous HF (aHF) solution of Cd(AsF 6)2. It crystallizes in a monoclinic P21/c space group with a = 9.4687(14) A, b = 9.2724(11) A, c = 10.5503(18) A, β = 104.887(7)°, and Z = 4. The coordination sphere of Cd consists of 7 + 2 fluorine atoms, which are in a capped trigonal-prismatic arrangement. The reaction between Cd(AsF6)2 and XeF 2 in aHF yields a solid white product at room temperature having the composition [Cd(XeF2)4](AsF6)2 after the excess XeF2 and solvent have been removed under dynamic vacuum. [Cd(XeF2)4](AsF6)2 crystallizes in the orthorhombic space group P21212 1, with a = 8.6482(6) A, b = 13.5555(11) A, c = 16.6312(14) A, and Z = 4. The coordination sphere of Cd consists of eight fluorine atoms, which are at the corners of a trigonal prism with two capped side faces.
