Abstract

Two series of isostructural intermetallics have been discovered in our search for new compounds with fused honeycomb motifs, both stable at elevated temperatures (1073 K). They crystallize with orthorhombic unit cells – La₄Co₄M (M = Sn, Sb, Te, Pb, Bi, SG Pbam, a = 8.247–8.315(2), b = 21.913–22.137(7), c = 4.750–4.664(2) Å, V = 850.5–869.5(4) Å³, Z = 4) and La₃Ni₃M (M = Al, Ga, SG Cmcm, a = 4.1790–4.2395(1), b = 10.4921–10.6426(6), c = 13.6399–13.7616(8) Å, V = 606.72–612.05(7), Z = 3). The crystal structures represent interesting variations of semiregular tilings of corrugated anionic layers and predominantly cationic zigzag motifs. The La₄Co₄M compounds reveal a complex type of ordering with a high degree of frustration as could be expected for the Kagomé -related lattices, while magnetic ordering in the La₃Ni₃M series is less evident. Electronic structure calculations have been performed for multiple compounds within both series revealing metallic character and visible local minima around the Fermi level. The bonding picture is characterized by nearly equal contributions from the anionic and the cationic components.
