Their complexing ability was studied by an optical method and from their electrical conductivity. The ESR spectra of the radicals were recorded. The limiting currents and reduction potentials of the hydrazines on a dropping mercury electrode were found. The charge and spin densities of the compounds were calculated by means of the Hiickel MO and MacLachlan methods. It was demonstrated that the hydrazines form unstable charge-transfer complexes in benzene-piperidine solutions; the charactristics of these complexes depend on the structure of the RR'N-NH-hydrazine residue Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Abramova, N.
