Phosphorus Compounds in Lower Coordination States Electrical Properties and Features of Structure

Abstract

P^I and P^II-derivatives have been investigated by electrical and electrooptical methods for the determination of the main parameters of multiple phosphorus bonds, polarity and polarizability, and on their basis spatial and electronic structure of these compounds has been studied. Experimental data on polarity and polarizability of phosphaalkynes P=CR, phosphaalkenes R¹ P=CR²R³, phosphyenes, diphosphenes, arsa- and stibaphosphenes R¹P=ER² (E = N, PI As, Sb) have been obtained. Polarities of P=C, P=C and P=E bonds have been determined. Multiple P=C and P=N bonds have considerable anisotropy of polarizability.
