Abstract
The influence of the replacement of hydrogen with deuterium in molecules of water of crystallization in the structure of the (CuSO4)(en) · 2H2O and (CuSO4)(en)·2D2O organometallic compound molecules on exchange interaction between copper ions was studied. The X-ray structural data and the data on angular anisotropy of the effective g-factor of Cu2+ ions in both compounds show that distortions of the initial structure caused by deuteration are minimum. A comparative analysis of the width of the exchange coupled EPR lines of the two compounds is indicative of a decrease in the exchange parameter in the deuterated sample, which substantiates the participation of H-bonds in exchange interactions in the systems studied.
