Advances in the understanding of the structure and physical properties of the cyclic radical F3CCSNSCCF3 (1) and related room temperature paramagnetic liquids

At room temp. (1) is a green paramagnetic liq. under a blue gas, that freezes to a black diamagnetic solid, which consists of tetramers of (1). The enthalpy of fusion, vaporization and sublimation are similar to those expected for a diamagnetic material, implying almost zero energy assocd. with the electron pairing in the solid state. There is a dramatic increase in vol. on melting of ca 20%, and that of the cyclic F3CCNSSN also a paramagnetic liq. is ca 30%. Exptl. and computational results as well as our present understanding of these properties including the nature of the liq. state will be presented. [on SciFinder (R)]
