ABOUT COMPARATIVE POLARITY OF As=N AND P=N GROUPS

abstract 0781204019 issue 78 pp. 222 – 233 30.04.2012 ru 1493
By the method of the dipole moments the connections of (p-XC6H4)3As=N-C6H4-Y series have been examined. The method of the vector-statistical analysis of the dipole moments helped to define the ranges and directions of the moments of (Сар)3As=N-Cар, (Сар)3As=N и N-Cар series. There has been shown that the substitution of the para-assistants X and Y in aromatic groups doesn't lead to an additional interaction influencing the electronic properties of the (Сар)3As=N-Cар group. The comparative analysis of the (Сар)3Э=N-Cар (Э=P, As) group moments specifies the essencial shift of the electron density to Сар(N) when replacing atom P to As

ABOUT POLARIZATIONS EFFECTS IN THE RANKS OF ЭХ3 MOLECULES

abstract 0991405018 issue 99 pp. 256 – 265 30.05.2014 ru 1559
Correlations between experimental dipoles moments and values of the difference of first potentials ionization of atoms and molecules (ΔE) for three -coordinated molecules of types ЭХ3 (Э=N, P, As, Sb are carried out; X=F, Cl, Br, I ) are described. Exponential functions of dependence μ= f(ΔE) for rows ЭF3 andЭCl3 are received. Within the valence of shell electron pair repulsion theory it is shown, that the molecular dipole moments can be divided to dipol moments of ions of separate atoms, which, naturally changing, are transferred in the ranks of molecules ЭХ3

BOUT REGULARITIES OF CHANGES OF VALENT ANGLES AND POTENTIALS OF IONIZATION IN THE RANKS OF ЭХ3 AND ЭХ2 MOLECULES

abstract 0951401056 issue 95 pp. 980 – 993 30.01.2014 ru 1345
Correlations between values of the differences of first potentials ionization of atoms and molecules (ΔE) and valency angels α for three coordinated molecules of types ЭХ3 (Э=N, P, As, Sb are carried out; X=F, Cl, Br, I, CH3), and also ЭХ2 (Э=O, S, Se, Te; X = CH3, SiH3, GeH3) are described in this article. It is shown, that the entered value ΔE can serve as additive measure of change of the valency angle α in the basic and raised stances. We have also established that the functional dependences correlate with changes in the of hybridization of orbitals and the R parameters characterizing the interaction of electronic pairs near the central Э atom

THE DIPOLE MOMENTS AND THE STRUCTURE OF THE FOUR-MEMBERED CLOSED-CHAIN ARSENIC COMPOUNDS

abstract 0781204020 issue 78 pp. 234 – 243 30.04.2012 ru 1129
By the method of dipole moments, there has been determined that the tri-coordinated arsenic derivatives (p-XC6H4AsN-R)2 with R= Bu-t in the liquor exist in a cis-form, as for R=С6Н4Х-p the trans-structure is being realized. As for tetra-coordinated derivatives [XC6H4As(S)NBu-t]2 the trans-form is also beeing observed. For ortho-substituted connections, the angles of flat surfaces rotation of benzene rings have been defined
