Abstract

Eu2(Ni2Si)3(Ni)2 crystallizes in the tetragonal P4_2/nmc space group. The structure is three-dimensional and consists of eight nickel molecules and one Eu2(Ni2Si)3 framework. In the Eu2(Ni2Si)3 framework, Eu2+ is bonded in a distorted single-bond geometry to two equivalent Ni1+ and one Si4- atom. Both Eu–Ni bond lengths are 2.79 Å. The Eu–Si bond length is 2.83 Å. There are two inequivalent Ni1+ sites. In the first Ni1+ site, Ni1+ is bonded in a 2-coordinate geometry to one Eu2+ and two equivalent Si4- atoms. There are one shorter (2.32 Å) and one longer (2.33 Å) Ni–Si bond lengths. In the second Ni1+ site, Ni1+ is bonded in a 4-coordinate geometry to four Si4- atoms. There are a spread of Ni–Si bond distances ranging from 2.18–2.55 Å. There are two inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a 10-coordinate geometry to six Ni1+ atoms. In the second Si4- site, Si4- is bonded in a 4-coordinate geometry to two equivalent Eu2+ and four equivalent Ni1+ atoms.
