Abstract

Dy10Si17 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are three inequivalent Dy sites. In the first Dy site, Dy is bonded in a 8-coordinate geometry to eleven Si atoms. There are a spread of Dy–Si bond distances ranging from 2.95–3.36 Å. In the second Dy site, Dy is bonded in a 8-coordinate geometry to ten Si atoms. There are a spread of Dy–Si bond distances ranging from 2.91–3.31 Å. In the third Dy site, Dy is bonded in a 10-coordinate geometry to ten Si atoms. There are a spread of Dy–Si bond distances ranging from 2.92–3.25 Å. There are ten inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to six Dy and three Si atoms. There are one shorter (2.39 Å) and two longer (2.40 Å) Si–Si bond lengths. In the second Si site, Si is bonded in a 8-coordinate geometry to six Dy and two equivalent Si atoms. In the third Si site, Si is bonded in a 8-coordinate geometry to six Dy and two Si atoms. The Si–Si bond length is 2.42 Å. In the fourth Si site, Si is bonded in a 8-coordinate geometry to six Dy and two Si atoms. There are one shorter (2.39 Å) and one longer (2.43 Å) Si–Si bond lengths. In the fifth Si site, Si is bonded in a 9-coordinate geometry to six Dy and three Si atoms. There are one shorter (2.35 Å) and two longer (2.44 Å) Si–Si bond lengths. In the sixth Si site, Si is bonded in a 9-coordinate geometry to six Dy and three Si atoms. The Si–Si bond length is 2.43 Å. In the seventh Si site, Si is bonded in a 9-coordinate geometry to six Dy and three Si atoms. There are one shorter (2.33 Å) and one longer (2.40 Å) Si–Si bond lengths. In the eighth Si site, Si is bonded in a 8-coordinate geometry to six Dy and two Si atoms. In the ninth Si site, Si is bonded in a 9-coordinate geometry to six Dy and three Si atoms. In the tenth Si site, Si is bonded in a 6-coordinate geometry to six Dy and two Si atoms.
