Crystal structure of partially Pd2+-exchanged zeolite X dehydrated in oxygen at 400 degrees C: formation of linear Pd2O3 clusters proposed to be HO-PdIV-OH in (Pd2)14(HOPdOPdOH4+)8(Na+)32-Si100Al92O384

Article Abstract:

Research designed to analyze the cation distribution in the crystal structure of fully dehydrated partially Pd2+-exchanged zeolite X is presented. It was possible to identify 30 Pd cations at sites I, I', another I' and III'.

Two crystal structures of fully dehydrated, fully Ag+ -exchanged zeolite X. Dehydration in oxygen prevents Ag+ reduction. Without oxygen, Ag8(super n+) (Td) and cyclo-Ag4(super m+) (near S4) form

Article Abstract:

Two crystal structures of fully dehydrated, fully Ag(super +) -exchanged zeolite X is determined by single crystal X-ray diffraction techniques. It is found that octahedral hexasilver molecules each coordinated to eight silver ions in the sodalite units of vacuum-dehydrated, fully Ag+ -exchanged zeolite A2.

Crystal structure of a benzene sorption complex of dehydrated fully Ca2+-exchanged zeolite x

Article Abstract:

A study was conducted to characterize the crystal structure of a benzene sorption complex of dehydrated fully Ca2+-exchanged zeolite x. The cubic space group Fd3 was utilized in the x-ray data collection. Full-matrix least-squares refinement was started at the atomic parameters of the framework atoms. Experimental results indicated that the maximum number of benzene molecules that can occupy each Na-Y supercage is between 4.9 and 5.2
