项目摘要

Transition metal complexes with dィイD14ィエD1-dィイD17ィエD1 configuration have a possibility of spin transition between an low-spin state and a high spin state. Particularly, in the case of mixed-valence complexes whose spin states lie in the spin-crossover region, new types of conjugated phenomena due to spin and charge are expected. From this viewpoint, we have synthesized the mixed valence complex, [(n-CィイD23ィエD2HィイD27ィエD2)ィイD24ィエD2N][FeィイD1IIィエD1FeィイD1IIIィエD1(dto)ィイD23ィエD2](dto = CィイD22ィエD2OィイD22ィエD2SィイD22ィエD2), and have investigated the magnetic properties by means of magnetic susceptibility, magnetization, ESR and ィイD157ィエD1Fe Mossbauer spectroscopy. From the measurements of magnetic susceptibility and magnetization as a function of temperature, [(n-CィイD23ィエD2HィイD27ィエD2)ィイD24ィエD2N][FeィイD1IIィエD1FeィイD1IIIィエD1(dto)ィイD23ィエD2] was found to show the ferromagnetic transition at 6 K and to show the reversible charge transfer phase transition at about 120 K. Moreover, we have investigated the spin transition of [Fe(NHィイD22ィエD2trz)ィイD23ィエD2](RSOィイD23ィエD2)22HィイD22ィエD2O. In the case of [Fe(NHィイD22ィエD2trz)ィイD23ィエD2](CィイD2nィエD2HィイD22n+1ィエD2SOィイD23ィエD2)ィイD22ィエD22HィイD22ィエD2O(n=1-9), the transition temperature becomes higher by about 80 K with increasing the length of alkyl chain of the counter anion, and then it saturated at n > 5. The even-odd effect was observed in the hysteresis width.In the case of three-dimensional mixed-valence system CsィイD22ィエD2AuィイD22ィエD2XィイD26ィエD2, we have discovered a photo-induced Au valence transition for CsィイD22ィエD2AuィイD22ィエD2BrィイD26ィエD2 under high pressure.
具有dィイD14ィエD 1-dィイD17ィエD 1构型的过渡金属络合物具有从低自旋态到高自旋态的自旋跃迁的可能性。特别是,对于自旋态位于自旋-交叉区的混合价络合物,由于自旋和电荷而产生的新类型的共轭现象是可望的。从这个角度出发,我们合成了混合价络合物[(n-CィイD23ィエD2HィイD27ィエD2)ィイD24ィエD2N][FeィイD1IIィエD1FeィイD1IIIィエD1(dto)ィイD23ィエD2](dto=CィイD22ィエD2OィイD22ィエD2SィイD22ィエD2),并用磁化率、磁化强度、电子自旋共振和ィイD157ィエD1Fe穆斯堡尔谱研究了它的磁性质。通过测量磁化率和磁化强度随温度的变化,发现[(n-CィイD23ィエD2HィイD27ィエD2)ィイD24ィエD2N][FeィイD1IIィエD1FeィイD1IIIィエD1(dto)ィイD23ィエD2]在6K出现铁磁相变,在约120K出现可逆的电荷转移相变。此外,我们还研究了[Fe(NHィイD22ィエD2trz)ィイD23ィエD2](RSOィイD23ィエD2)22HィイD22ィエD2O.的自旋相变在[Fe(NHィイD22ィエD2trz)ィイD23ィエD2](CィイD2nィエD2HィイD22n+1ィエD2SOィイD23ィエD2)ィイD22ィエD22HィイD22ィエD2O(n=1-9),的情况下,随着反阴离子烷基链长的增加,转变温度升高约80K,然后在n&gT达到饱和;在三维混合价体系CsィイD22ィエD2AuィイD22ィエD2XィイD26ィエD2中,我们发现CsィイD22ィエD2AuィイD22ィエD2BrD26ィイD2在高压下发生了光致金价跃迁。
