  • Although intermetallic compounds and alloys feature metal atoms bonded solely to other metal atoms, this motif is unusual in molecular compounds. Now, three compounds with lanthanide metals surrounded by transition metal atoms have been made. Although reactive, they mimic intermetallic bonding and form a conceptual link from coordination compounds.

  • Half-and full-Heusler compounds are considered as independent phases with a natural composition gap. Here the authors report the discovery of half-Heusler-like TiRu1+xSb with wide continuous compositions falling in the gap region and tunable p-to n-type semiconducting thermoelectrics.

  • Lead telluride is an important thermoelectric material but its metal-to-semiconductor transition above 230 °C is not fully understood. Here, atomic-resolution transmission electron microscopy provides structural insights into this transition, explaining the metallic behavior by a dislocation network within the rock salt structure.

  • Phonon lifetime is a fundamental parameter of thermal transport however its determination is challenging. Using inelastic neutron scattering and the neutron resonant spin-echo technique, Lory et al. determine the acoustic phonon lifetime in a single crystal of clathrate Ba7.81Ge40.67Au5.33.

  • Intermetallic compounds of bismuth exhibit superconductivity and topological phenomena, with their formation under extreme conditions having been extensively investigated. Here, the authors report the synthesis of Mg5Bi3Hx at 4–5 GPa and 973–1273 K, observing H at partially occupied interstitial positions, following the Zintl concept.

  • Materials with a chiral crystal structure are of great interest due to potentially non-trivial structure-property relations. Here, electron microscopy and crystallographic analysis, supported by quantum chemical calculations, shed light on the conversion of the crystal structure of CoSi accompanying a change in handedness.
