摘要：

Low-temperature magnetic measurements on powdered samples of the title nitronyl nitroxide radical (see figure) are reported. Evidence for ferromagnetic order with a T-c of ca. 0.2 K is found. It is proposed that the diffuse electronic cloud of the sulfur atom in the radical substituent generates sufficiently strong ferromagnetic interactions even at large distances.
