“…Lithium-magnesium alloy castings are up to 30% lighter than castings from aluminium alloys and 50-70% lighter than castings from iron alloys (Shin & Carter, 2014;Haferkamp et al, 2000;Aghion & Bronfin, 2000;Pezda, 2009). New materials developed based on magnesium are promising candidates for potential hydrogen-storage materials (Herbst & Meyer, 2010;Pavlyuk et al, 2013;Verbovyts'kyi & Zavalii, 2016;Verbovytskyy et al, 2020Verbovytskyy et al, , 2021. For these materials, the ability to absorb hydrogen is much greater than for previously known modified phases based on LaNi 5 , LaNi 5-x Zn x (Giza et al, 2009a;Pavlyuk et al, 1997) and ZrNi 5-x Zn x (Giza et al, 2001(Giza et al, , 2009b.…”

The new ternary gallide MgMn4Ga18 (magnesium tetramanganese octadecagallium) was synthesized and its crystal structure determined by means of single-crystal X-ray diffraction. The MgMn4Ga18 structure can be described as that of a three core–shell cluster compound. The Mg atoms are surrounded by 16 adjacent Ga atoms, [MgGa16], and the respective coordination polyhedron is an octadecahedron. This [MgGa16] octadecahedron is encapsulated inside a [Ga32] icohexahedron, which is in turn encapsulated inside a [Ga40] pentacontaoctahedron. As a result, a three core–shell cluster, [MgGa16@Ga32@Ga40], is identified. Electronic structure calculations were performed by means of the TB-LMTO-ASA program and additionally confirm the existence of the core–shell packing of the clusters.
