Magnetic blocking in extended metal atom chains: A pentachromium(ii) complex behaving as a single-molecule magnet

Abstract

Compound [Cr5(tpda)4Cl2] (H2tpda = N2, N6-di(pyridin-2-yl)pyridine-2,6-diamine), an Extended Metal Atom Chain complex featuring two quadruply-bonded (Cr2) units, exhibits field-induced slow relaxation of its magnetization arising from the terminal chromium(ii) ion and provides the first example of a chromium(ii)-based Single-Molecule Magnet. © 2014 The Royal Society of Chemistry.
