Saturnene revealed : X-ray crystal structure of D5d-C60F20 formed in reactions of C60 with AxMFy fluorinating agents (A=Alkali Metal; M=3d Metal).

The reactions between C60 and the AxMFy were sistematically carried out to find out how the degree of fluorination (i.e., the value of n in the C60Fn products) can be controlled by varying the oxidation state of the metal or by “adding” alkali metal fluorides (i.e., by using a mechanical mixture of AF and MFx or a ternary salt AxMFy). Crystal structure of C60F20 was also determined.

Selective aromatic C-F and C-H bond activation with silylenes of different coordinate silicon.

Reactions between silylenes and fluorinated aromatic compounds showed to be stereospecific. Similar mechanisms are almost unknown in organometallic chemistry. Products can be used as starting material for transfer of different fluorinated groups to organic substrates.

The generalized approach to electrolytic systems – the generalized equivalent mass concept

The equivalent mass concepts (advocated by IUPAC) applied in all calculations referred to titrations is based on chemical reaction notation, while generalized equivalent mass (GEM) concept is based on the generalized approach to electrolytic systems (GATES). The comparison of EM and GEM concepts is presented, as well as the major advantage, which is titrations in complex titration systems using the later approach, discussed. Examples of titrations are presented.

Analysis of the reliability of the measurement and pressure regulation installation for the natural gas.

Analysis of the failure mechanisms and related statistical analysis of the failure rates of the individual components of the typical installation revealed that for the final reliability and availability, the disturbances from the outside of the installation are key and not its components.

A Genuine Sulfate of Divalent Silver with Anomalously Strong One-Dimensional Antiferromagnetic Interactions

Black AgSO4 could be prepared by a methathetic reaction of Ag(SbF6)2 and K2SO4 in anhydrous HF or by the reaction of AgF2 with H2SO4. According to thermoanalytical studies, the product is metastable and decomposes above 120 oC with evolution of O2. The triclinic crystal structure of AgSO4 contains planar rectangular AgO4 units that are connected by SO4 tetrahedra to form a three-dimensional network. Measurements of the temperature-dependent magnetic susceptibility indicate that there are strong antiferromagnetic interactions between the neighbouring Ag2+ cations.
