Abstract

Highly metallic compounds with a quasi-one-dimensional structure, the new ternary compounds Ln₂Al₃Si₂ (Ln=Ho, Er, Tm) are synthesized in molten aluminum from lanthanoid and silicon as reagents. Their structures show a formally [Al₃Si₂]^6- framework that contains infinite Al zigzag chains and Si-Si dimers and accommodates rows of Ln³⁺ ions in parallel tunnels. The compounds exhibit metamagnetic transitions at high magnetic fields.
