High-spin supramolecular pair of Mn(II)/thiazyl radical complexes.

چکیده
The Mn(hfac)(2) complex of the paramagnetic 4-(benzoxazol-2'-yl)-1,2,3,5-dithiadiazolyl ligand is reported (hfac = 1,1,1,5,5,5-hexafluoroacetylacetonato-). The Mn(ii) and radical ligand spins are coupled antiferromagnetically (AF) in the coordination complex. Short sulfur-oxygen contacts between molecules provide an efficient pathway for AF coupling between the radical ligand of one molecule and the Mn(ii) of a neighbouring molecule, resulting in a large total spin ground state (S(T) = 4) for a pair of molecules.
