    基于噻唑二硫醇金配合物的单组分分子金属
    摘要:
    单组分分子导体已从基于 N-乙基-1,3-噻唑啉-2-硫酮-4,5-二硫醇 (Et-thiazdt) 配体的单阴离子金双 (dithiolene) 配合物的电结晶中分离出来。该系统的晶体结构展示了由平面分子的平行均匀一维堆叠构建的层。在室温和环境压力下,该系统是半导体 (0.33 S x cm(-1)),具有很小的活化能。然而,单晶电导率是强烈的压力依赖达到 1000 S x cm(-1) 在 21 kbar。在 13 kbar 时,半导体和金属状态之间存在交叉。因此,本系统是第一个没有TTF二硫醇配体的充分表征的单组分分子金属。第一性原理 DFT 计算表明基态是反铁磁性的,带隙非常小。压力对电子结构影响的模拟为观察到的电导率变化提供了基本原理,并提供了有关如何进一步稳定系统金属状态的见解。

    Anisotropic Chemical Pressure Effects in Single-Component Molecular Metals Based on Radical Dithiolene and Diselenolene Gold Complexes
    摘要:
    On the basis of the reported radical neutral complex [Au(Et-thiazdt)(2)] (Et-thiazdt = N-ethyl-1,3-thiazoline-2-thione-4,5-dithiolate), a series of single-component conductors derived from [Au(Et-thiazdt)(2)], also noted as [AuS4(=S)(2)], has been developed, by replacing the outer sulfur atoms of the thiazoline-2-thione rings by oxygen atoms and/or by replacing the coordinating sulfur atoms by selenium atoms toward the corresponding diselenolene complexes. Comparison of the X-ray crystal structures and transport properties of the four isostructural complexes, noted as [AuS4(=S)(2)], [AuS4(=O)(2)], [AuSe4(=S)(2)], and [AuSe4(=O)(2)], shows that the oxygen substitution on the outer thiazoline ring actually decreases the conductivity by a factor of 100, despite a contracted unit cell volume reflecting a positive chemical pressure effect. On the other hand, the S/Se substitution increases the conductivity by a factor of 100, and the pressure needed to transform these semiconductors into the metallic state is shifted from 13 kbar in [AuS4(=S)(2)] to only approximate to 6 kbar in [AuSe4(=S)(2)] Analysis of unit cell evolutions and ab initio band structure calculations demonstrates the strongly anisotropic nature of this chemical pressure effect and provides an explanation for the observed changes in conductivity. The greater sensitivity of these neutral single-component conductors to external pressure, as compared with "classical" radical salts, is also highlighted.
