Ferromagnetic ordering in the organic radical cation salt BBDTA•Au(CN)2 at 8.2 K

An organic radical cation salt, BBDTA center dot Au(CN)(2), with a slipped pi-stacking columnar structure and intercolumnar short contacts, shows ferromagnetic ordering at 8.2 K, the highest reported temperature among the BBDTA(+) cation salts.
