Abstract

YbSi 2 and the derivatives YbT xSi 2-x (T = Cr, Fe, Co) crystallizing in the α-ThSi 2 structure type were obtained as single crystals from reactions run in liquid indium. All silicides were investigated by single-crystal X-ray diffraction, I4 1/amd space group and the lattice constants are: a = 3.9868(6) Å and c = 13.541(3) Å for YbSi 2, a = 4.0123(6) Å and c = 13.542(3) Å for YbCr 0.27Si 1.73, a = 4.0142(6) Å and c = 13.830(3) Å for YbCr 0.71Si 1.29, a = 4.0080(6) Å and c = 13.751(3) Å for YbFe 0.34Si 1.66, and a = 4.0036(6) Å, c = 13.707(3) Å for YbCo 0.21Si 1.79. YbSi 2 and YbT xSi 2-x compounds are polar intermetallics with three-dimensional Si and M (T+Si) polyanion sub-networks, respectively, filled with ytterbium atoms. The degree of substitution of transition metal at the silicon site is signficant and leads to changes in the average bond lengths and bond angles substantially.
