  after column chromatography. The radical yields depended on the reaction time and the molar ratio of azo compounds to nitroso compounds. In the same manner, acetyl- and cyano-group-carrying N-tert-alkoxyarylaminyls were generated by the reaction of 2-phenyl-4-(4-acetylphenyl)-6-tert-butylnitrosobenzene and 2-phenyl-4-(4-cyanophenyl)-6-tert-butylnitrosobenzene with 5a and 5b, and they were isolated as

  We designed and synthesized a triphenylphenylnitroxide–(nitronyl nitroxide) dyad with a structure isoelectronic with trimethylenemethane. Crystal structure analysis demonstrated that the dihedral angle between the nitroxide and nitronyl nitroxide moieties was excessively small due to the steric effects of the triphenylphenyl moiety. The coplanarity of the two radical systems induced an excessively

  我们设计并合成了三苯基硝基氧-(硝酰基硝基氧)二元组，其结构与三亚甲基甲烷等电子。晶体结构分析表明，由于三苯基苯基部分的空间效应，硝基氧和硝酰基硝基氧部分之间的二面角过小。两个自由基系统的共面性导致了过强的铁磁分子内相互作用（2 J / k B ≥ +2000 K；H = -2 J S 1/2 • S 1/2）。

  Five N-aryl-N-pyridylaminoxyls, which have no substituent (PhNOpy), one substituent (MeOPhNOpy and tert-BuPhNOpy) at the 4-position, and three substituents (TPPNOpy and TBPNOpy) at the 2, 4, and 6-positions of the phenyl ring, were prepared as new ligands for cobalt-aminoxyl heterospin systems. The 1:4 complexes, [Co(NCS)(2)(PhNOpy)(4)] (1), [Co(NCS)(2)(MeOPhNOpy)(4)](2), [Co(NCS)(2)(tertBuPhNOpy)(4)] (3), [Co(NCS)(2)(TPPNOpy)(4)] (4), [Co(NCS)(2)(TBPNOpy)(4)] (5a), and [Co(NCO)(2)(TBPNOpy)(4)] (5b), were obtained as single crystals. The molecular geometry revealed by X-ray crystallography for all complexes except 4 is a compressed octahedron. In the crystal structure of 1, 2, and 3, the organic spin centers have various short contacts within 4 A with the neighboring molecules to form 3D and 2D spin networks. On the other hand, complexes 5a and 5b have no significant short intermolecular contacts, indicating that they are magnetically isolated. 1 and 2 behaved as a 3D antiferromagnet with a Neel temperature, T-N, of 22 K and as a weak 3D antiferromagnet with a T-N of 2.9 K and a spin-flop field at 1.9 K, H-sp(1.9), of 0.7 kOe, respectively. 3 was a canted 2D antiferromagnet,(a weak ferromagnet) with T-N = 4.8 K and showed a hysteresis loop with a coercive force, H-c, of 1.3 kOe at 1.9 K. On the other hand, the trisubstituted complexes 4, 5a, and 5b functioned as single-molecule magnets (SMMs). 5b had an effective activation barrier, U-eff, value of 28 K in a microcrystalline state and 48 K in a frozen solution.
