资源简介：
Metal-radical alternating chains [Co(hfac)2HNN]n crystallized in two
morphs containing repeating all-cis (α) and cis,cis,trans (β)
configurations with respect to the OHNN−Co−OHNN geometry (HNN
= 4,4,5,5-tetramethylimidazolin-1-oxyl 3-oxide). Both phases
showed magnetization jumps with hysteresis at 2 K. The α phase
has a relatively high activation energy of magnetization reorientation
(193 K).
