Mechanochemical reaction of cluster coordination polymers
(Q=S, Se) with solid
leads to the cluster core excision with the formation of anionic complexes
. Extraction of the reaction mixture with water followed by crystallization gives crystalline
(main product) and
(1) (minor product). In the case of the Se cluster, the
complex could not be isolated, and the treatment of the aqueous extract with PPh3 gave
(2) in a low yield. Alternatively, it was obtained from
and
in high yield. Both 1 and 2 were characterized by X-ray structure analysis.
Dedicated to Academician I. I. Moiseev on the occasion of his 75th birthday and in recognition of his outstanding contribution
to cluster chemistry. 相似文献

The article discusses the properties of several model zirconium dioxide complexes (ZrO(2))(n)() intercalated into the interlayer space of montmorillonite clay. Grand canonical Monte Carlo simulation was used in a series of numerical experiments during analysis of the low-temperature nitrogen adsorption in the micropores thus generated. The goal of such experiments was to determine the geometrical parameters of introduced molecular complexes of different types inside micropores of various widths. The obtained information was used to characterize textural and structural properties of three pillared interlayer materials prepared by using pillaring species synthesized via aging of zirconyl chloride solutions containing as additives chlorides of Ca, Sr, or Ba. It was found that in the cases of Ba and Ca the interlayer micropores are filled with isolated tetramers (ZrO(2))(4). Meanwhile, the presence of Sr in the pillaring solution, most likely, favors the preservation of larger sheetlike complexes (ZrO(2))(8). 相似文献
