SiEu crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded in a 7-coordinate geometry to seven equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to seven equivalent Eu(1) and two equivalent Si(1) atoms.
SiEu crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded in a 7-coordinate geometry to seven equivalent Si(1) atoms. There are four shorter (3.15 Å) and three longer (3.25 Å) Eu(1)-Si(1) bond lengths. Si(1) is bonded in a 9-coordinate geometry to seven equivalent Eu(1) and two equivalent Si(1) atoms. Both Si(1)-Si(1) bond lengths are 2.45 Å.
