摘要：

A new ambient-pressure organic superconducting charge-transfer salt, (BEDT-TTF)2(NH4)Hg(SCN)4, is reported. The unit cell parameters of this salt indicate that it is isostructural to (BEDT-TTF)2KHg(SCN)4, which possesses an α-type packing motif. The broad ESR line width of 56 to 84 G at 300 K as well as its temperature dependence further indicates that this salt has an α-type packing. Conductivity measurements show that (BEDT-TTF)2(NH4)Hg(SCN)4 is metallic to low temperatures and inductive studies by RF penetration depth measurements demonstrate that it is superconducting with an onset at 1.15 K. © 1990.
