Hf6Al7 and Hf4.44(1)Nb1.56(1)Al7—the First Fully Ordered Main Group Metal Containing W6Fe7 Type Compound and its Ternary Coloring Variant

Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 11, July 22, 2025.
Hf4Nb2Al7 and Hf6Al7 were synthesized from the elements and crystallize in the rhombohedral W6Fe7 type structure. Single crystals showed obverse‐reverse twinning. In addition, 27Al NMR investigations, magnetic measurements and quantum‐chemical calculations were conducted. Attempts to synthesize Hf4NbAl7 led to the discovery of nominal Hf4Nb2Al7 instead
