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

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

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

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
