Abstract

Single crystals of two new compounds, Eu 3InP 3 and Eu 3In 2P 4, were prepared by In flux synthesis. Eu 3InP 3 crystallizes in the Pnma orthorhombic space group with a = 12.6517(15) Å, b = 4.2683(5) Å, c = 13.5643(14) Å, and Z = 4 while Eu 3In 2P 4 belongs to Pnnm space group, a = 6.6999(6) Å, b = 16.1019(13) Å, c = 4.2725(4) Å, and Z = 2. These two compounds are isotypic to the main group compounds Sr 3InP 3 and Sr 3In 2P 4 respectively. Both structures consist of distorted In-P tetrahedra and isolated Eu 2+ ions. In Eu 3InP 3 these tetrahedra share corners to form one-dimensional chains. The Eu 2+ ions occupy three different sites, and form a complicated network containing some triangles. In Eu 3In 2P 4 these tetrahedra form edge-shared dimers, and these dimers form chains. Eu 3InP 3 shows unusual magnetic properties: there are three magnetic ordering transitions at 14 K, 10.4 K, and around 5 K and the magnetization curve shows steps in the low temperature region. Eu 3In 2P 4 magnetically orders at 14.5 K. Its magnetization curve saturates at around IT. Eu 3InP 3 and Eu 3In 2P 4 are both semiconductors.
