合成了首个以顺磁性三（草酸）钌酸盐为阴离子的BEDT-TTF自由基阳离子盐为基的分子超导体β " -(BEDT-TTF)4Kx(h30)1−x[RuIII(ox)3]C6H5Br (x ~ 0.8)，研究了其晶体结构、电子结构、输运和磁输运性质。单晶具有单斜C2/c对称性和导电BEDT-TTF层的β " -填料。发现样品是超导体，Tc = 2.8-6.3 K（取决于样品）。在7 ~ 17 t范围内观察到明显的舒布尼科夫-德哈斯振荡，振荡的傅立叶谱主要由两个频率组成，分别对应于布里渊区6.3%和0.85%的费米面截面。第一个精度较好，对应于计算截面的7.5%，讨论了第二个的起源。还合成并研究了半导体正交相' pseudo-κ ' -(BEDT-TTF)4Kx(h30o)1−x[RuIII(ox)3]C6H5CN。
The first molecular superconductor based on BEDT-TTF radical cation salt with the paramagnetic tris(oxalato)ruthenate anion, β′′-(BEDT-TTF)4Kx(H3O)1−x[RuIII(ox)3]C6H5Br (x ∼ 0.8), is synthesized and its crystal and electronic structure as well as transport and magnetotransport properties are studied. The single crystals have monoclinic C2/c symmetry and β′′-packing of the conducting BEDT-TTF layer. The samples were found to be superconductors with Tc = 2.8–6.3 K (depending on the sample). Well pronounced Shubnikov–de Haas oscillations are observed in the field range 7–17 T. The Fourier spectrum of the oscillations mainly consists of two frequencies, which correspond to the Fermi surface cross sections 6.3% and 0.85% of the Brillouin zone. The first one with good accuracy corresponds to the calculated cross section 7.5%, the origin of the second one is discussed. Semiconducting orthorhombic phase ‘pseudo-κ’-(BEDT-TTF)4Kx(H3O)1−x[RuIII(ox)3]C6H5CN is also synthesized and studied.
