Abstract
The polycrystalline sample of the title radical has a positive Weiss c onstant of 0.63 K. The ac susceptibility measurements indicated a ferr omagnetic phase transition at about 0.4 K. The magnetization measured at 80 mK (below T-c) showed a characteristic curve of a ferromagnet wi th a small hysteresis. The X-ray crystal structure analysis at room te mperature revealed a two-dimensional network of the N-O sites (O...O d istances are 5.96 and 6.09 Angstrom) with an inter-sheet distance of 1 4.2 Angstrom.
