Changeover in a multimodal copper(ii) catenate as monitored by EPR spectroscopy

Abstract

The electrochemically triggered rearrangement of a copper catenate is monitored by EPR spectroscopy; the initially generated tetrahedral copper(II) complex (with higher g-factor components and lower metal hyperfine splitting) is converted to a stable five-coordinate copper(II) species, within a few minutes at room temperature, in anhydrous MeCN.
