"Spin tweaking" of a high-spin molecule: An Mn25 single-molecule magnet with an S = 6 1/2 ground state

Abstract

(Figure Presented) Spin doctoring: The already high spin of S = 5 1/2 of a Mn25 complex has been pushed even higher, by approximately 20%, to S = 6 1/2 by targeted substitution of the azide ligands with an N,O-chelating group. This significant adjustment, or tweaking, of the spin suggests the general possibility that a given type of complicated, high-nuclearity, high-spin molecule can exhibit differing ground states by appropriate modification of the peripheral ligation. © 2007 Wiley-VCH Verlag GmbH & Co.
