A novel paramagnetic dithiadiazolyl radical: Crystal structure and magnetic properties of p-BrC6F4CNSSN•

Abstract

The dithiadiazolyl radical p-BrC₆F₄CNSSN· 2 retains its monomeric nature in the solid state; variable temperature magnetic studies on 2 indicate Curie–Weiss behaviour (θ = –27 K) above 60 K with an effective magnetic moment of 1.45 µ_B at room temperature; the absence of long-range magnetic order down to 1.8 K is attributed to the low dimensionality of the magnetic exchange pathway predicted on the basis of the inter-molecular S‥N interactions.
