Honeycomb motifs

An article in honor of Vitalij K. Pecharsky – when looking for honeycomb motifs in intermetallics our team discovered two new isostructural series of intermetallics: La4Co4M (M = Sn, Sb, Te, Pb, Bi) and La3Ni3M (M = Al, Ga):

Intermetallics of 4:4:1 and 3:3:1 series in La–(Co,Ni)–M (M = Bi, Pb, Te, Sb, Sn and Ga, Al) systems and their properties
