Ln 2 Al 3 Si 2 (Ln=Ho, Er, Tm): New Silicides from Molten Aluminum-Determination of the Al/Si Distribution with Neutron Crystallography and Metamagnetic Transitions

Highly metallic compounds with a quasi-one-dimensional structure, the new ternary compounds Ln Al Si (Ln=Ho, Er, Tm) are synthesized in molten aluminum from lanthanoid and silicon as reagents. Their structures show a formally [Al Si ] framework that contains infinite Al zigzag chains and Si-Si dimer...

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