No full textThe article views the notion religious extremism as a phenomenon. The author shows the ideological-theoretical aspect, oriented at Islamic concepts, as one of the most important aspects of struggling against Islamic extremism and terrorism. The article also shows the main directions of state structures activities in extremism counteraction

No full textRegional circumstances play a crucial role in socio-economic situation of labour market. Its competitiveness depends not only on measurable factors, but also on soft factors. Nowadays more and more researchers and scientists pay their attention to the importance of social capital. Fragmentariness of scientific knowledge based on empirical investigation con-ducted in Polish reality, makes the author to prepare own empirical research in this field. The aim of the paper is to present the result of the research conducted in Southern Poland in late-2004. The region was defined as the area of two provinces Małopolska and Śląsk, but the choice was not stochastic. These provinces makes one region according to NUTS-1 nomen-clature. The research was conducted on a random sample of 109 small and medium-sized en-terprises localized in Southern Poland. Descriptive statistics (arithmetic average, median, mo-dal, quartile) as well as verifying tools (chi-square statistics, U Mann Whitney test) were used in order to verify the hypotheses.regional labour markets (R23), geographic labour mobility (J61), regional economics (R19), personnel economics (M59)
Supramolecular aggregation of lead(II) perchlorate and a thiosemicarbazide derivative linked by a myriad of non-covalent interactions
No full textIn this work, we report on a new lead(II) coordination complex [Pb2L2(CH3CN)(ClO4)2]·2H2O (1·2H2O), which was readily synthesized from a mixture of Pb(ClO4)2·3H2O and 1-(pyridine-2-yl)benzylidene-4-phenylthiosemicarbazide (HL). The crystal structure analysis of 1·2H2O evidenced that the lead(II) cation is N,N',S-chelated by the tridentate pincer type L with formation of a [PbL]+ coordination species, which dimerizes through a couple of reciprocal bridging Pb–S bonds, yielding the [Pb2L2]2+ complex cation. The metal centers within this cation are linked by two Pb∙∙∙N tetrel bonds through the bridging acetonitrile molecule with the formation of a [Pb2L2(CH3CN)]2+ building unit. These units are glued by reciprocal Pb∙∙∙S tetrel bonds, yielding a 1D supramolecular polymeric chain. The lead(II) cations interact also with disordered oxygen atoms of both the minor and major occupancies of the perchlorate anions either through covalent Pb–O bonds or Pb∙∙∙O tetrel bonds, respectively. 1D polymeric chains resemble an expanded hexagonal projection and span along the a axis, yielding a grid-like crystal packing, where the cavities are filled by lattice water molecules. The interactions have been studied using DFT calculations and characterized by using the quantum theory of atoms-in-molecules (QTAIM) and the non-covalent interaction plot (NCIplot) computational tools. © 2022 The Author(s)Ministry of Education and Science of the Russian Federation, Minobrnauka: 720000Ф.99.1, БЗ85AA13000; European Regional Development Fund, ERDF; Agencia Estatal de Investigación, AEI: PID2020-115637GB-I00A.
