Materials Data on Eu2Si3Au by Materials Project
Eu2AuSi3 is hexagonal omega structure-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Eu+2.50+ is bonded to three equivalent Au1- and nine Si+1.33- atoms to form a mixture of face and edge-sharing EuSi9Au3 cuboctahedra. All Eu–Au bond lengths are 3.28 Å. There are three shorter (3.28 Å) and six longer (3.31 Å) Eu–Si bond lengths. Au1- is bonded in a distorted trigonal planar geometry to six equivalent Eu+2.50+ and three equivalent Si+1.33- atoms. All Au–Si bond lengths are 2.44 Å. There are three inequivalent Si+1.33- sites. In the first Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to six equivalent Eu+2.50+ and three equivalent Si+1.33- atoms. All Si–Si bond lengths are 2.44 Å. In the second Si+1.33- site, Si+1.33- is bonded in a distorted trigonal planar geometry to six equivalent Eu+2.50+ and three equivalent Au1- atoms. In the third Si+1.33- site, Si+1.33- is bonded in a 9-coordinate geometry to six equivalent Eu+2.50+ and three equivalent Si+1.33- atoms.
