“…The resultant crystals had silver luster and needlelike morphology (see Figure c,d). Similar to the other mercury-based compounds, ,,− the YHg 3 and LuHg 3 phases exhibited extreme air- and moisture-sensitivity, thereby resulting in an immediate decomposition even after short exposure to air (Figure ).…”

Amalgams have played an important role in fundamental and applied solid-state chemistry and physics because of the diversity of crystallographic features and properties that they have to offer. Moreover, their peculiar chemical properties can sometimes give rise to unconventional superconducting or magnetic ground states. In the current work, we present an in-depth analysis of single crystals of YHg 3 and LuHg 3 (Mg 3 Cd structure type, space group P6 3 /mmc). Both compounds show superconductivity below T c = 1 ± 0.1 K (YHg 3 ) and T c = 1.2 ± 0.1 K (LuHg 3 ). Given the high air-sensitivity and toxicity of these compounds, this study was only possible using a number of dedicated experimental techniques.

“…Unlike the Cu 3 Hg phase, both YHg 3 and LuHg 3 are highly air- and moisture-sensitive, decomposing quickly even after minute exposure to air. This is also the case for many other Hg-containing materials, ,,− which thus require a special synthesis and handling laboratory environment…”

“…All sample preparation and handling were performed in a specialized laboratory, equipped with an argon-filled glovebox system (MBraun, p (H 2 O/O 2 ) < 0.1 ppm). 69 Single crystals of LaHg 6.4 were synthesized from La (pieces, Ames Laboratory, >99.9%) and Hg (ChemPur, 99.999%) using the self-flux method. The La chunks and Hg droplets, mixed in the 5:95 ratio, were sealed in Ta tubes under an Ar atmosphere ( Figure S1a,b ).…”

The influence of structural disorder on superconductivity is not yet fully understood. A concurrent examination of crystallographic and physical properties of LaHg 6.4 reveals that this material enters a superconducting state below T c = 2.4 K while showing crystallographic disorder in one dimension. Lanthanum mercuride, which crystallizes in a new structure type (space group Cmcm , a = 9.779(2) Å, b = 28.891(4) Å, c = 5.0012(8) Å, Z = 8), has remained out of reach for nearly 50 years. In this crystal structure, strong disorder is present in the channels that propagate along the [001] direction. By implementing a combination of cutting-edge synthesis and characterization techniques, we were able to circumvent the complexity associated with the low formation temperature and chemical reactivity of this substance and study the superconductivity of LaHg 6.4 in detail.
