Abstract
The structure of [Co(L-Rha)3-mn)]Br2.2CH3OH, where (Rhah-tren is tris(N-rhamnosyl-2-aminoethyl)amine, was elucidated by X-ray crystallography, which confirmed the unprecedented configurational inversion of [Co((Rha)3-tren)]2+, around the metal center reversibly by an addition and a removal of sulfate.
