采用电结晶法制备了一种新型锰配合物[Mn(Pc)(CN)]2O。该材料是一种单组分分子导体，具有半导体性能，室温电导率为4.5 × 10-3S cm-1。此外，在室温下，由于传导π电子和局域自旋之间的相互作用，我们观察到负磁电阻。x射线结构分析和红外吸收光谱显示结构紊乱。磁化率测量表明，由于这种结构紊乱，两个锰原子的自旋态不相等。
A new manganese complex, [Mn(Pc)(CN)]2O, was prepared by an electrocrystallization method. This material is a single-component molecular conductor that displays semiconducting behavior with room temperature conductivity of 4.5 × 10–3S cm–1. Furthermore, we observed negative magnetoresistance at room temperature due to interaction between conduction π electrons and localized d spins. X-ray structural analysis and IR absorption spectroscopy indicated structural disorder. The magnetic susceptibility measurements suggested the unequal spin states of two manganese atoms owing to this structural disorder.
