By X-ray diffraction the crystal and molecular structure of N-(1-silatranylmethyl)phthalimide (SMP) is determined. The coordination polyhedron of the silicon atom in SMP, as in all silatranes, is a trigonal bipyramide; the phthalimide cycle is planar. The data presented indicate that the silatranylmethyl group almost does not affect the geometry of the phthalimide moiety. Original Russian Text Copyright © 2011 by M. G. Voronkov, É. A. Zel'bst, A.

We examine the contemporary denudation cycles in the steppes of Khakassia, including the phase of integration of matter in the system and of the nival-proluvial removal, and the deflation phase of long-range transport of matter from the Minusinskaya depression. The cartographic model for the contemporary functioning of denudation systems is presented. © 2010.

The crystal and molecular structure of 4-chloro(benzoyloxymethyl) trifluorosilane 4-ClC6H4COOCH2SiF3 was redetermined using X-ray diffraction. The coordination polyhedron of the silicon atom in this structure is a trigonal bipyramid. The length of the axial O → Si coordination bond is 2.074(1) Å. © 2013 Pleiades Publishing, Ltd.

The magnetization reversal and magnetic impedance (MI) of films and film elements based on Fe19Ni81 and Fe72. 5Cu1. 1Nb1. 9Mo1. 5Si14. 2B8. 7 alloys with a varied thickness, heat-treatment temperature, and the number of thin Cu interlayers are studied. The dependences of the coercive force and the magnitude of MI on these parameters are found. Layered structuring is shown to be an effective method for improving the functional characteristics of MI elements. In elements containing nanocrystalline Fe19Ni81 layers, this is related to the restructuring of a magnetic structure; in elements containing amorphous Fe72. 5Cu1. 1Nb1. 9Mo1. 5Si14. 2B8. 7 layers, this improvement is likely to be caused by a decrease in the effective electrical resistivity. © 2013 Pleiades Publishing, Ltd.
