(18-Crown-6)(trifluoromethanesulfonato)sodium [PDF]

open access: yesActa Crystallographica Section E, 2010
The title compound, [Na(CF3O3S)(C12H24O6)], features a sodium cation that is coordinated by eight O atoms in an irregular hexagonal bipyramidal environment. The equatorial positions are occupied by the six O atoms of an 18-crown-6 ether ring.

Probing cations recognized by a crown ether with the 3D-RISM theory. II. 18-crown-6 ether [PDF]

open access: yesCondensed Matter Physics, 2007
In the previous study, we investigated the cation recognition by12-crown-4 ether with the 3D-RISM theory [Ikuta, Y. et al., Chem. Phys. Lett., 2007, 433, 403], and showed the applicability of the theory to the problem.

Isolation of a Californium(II) Crown-Ether Complex [PDF]

open access: yes, 2022
Californium (Z = 98) is the first member of the actinide series displaying metastability of the 2+ oxidation state. Understanding the origin of this chemical behavior requires characterizing Cf(II) materials, but isolating a complex with this state has ...
