HfSi2 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. Hf(1) is bonded in a 10-coordinate geometry to four equivalent Si(1) and six equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 8-coordinate geometry to four equivalent Hf(1) and four equivalent Si(1) atoms. In the second Si site, Si(2) is bonded in a 8-coordinate geometry to six equivalent Hf(1) and two equivalent Si(2) atoms.
HfSi2 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. Hf(1) is bonded in a 10-coordinate geometry to four equivalent Si(1) and six equivalent Si(2) atoms. There are two shorter (2.78 Å) and two longer (2.79 Å) Hf(1)-Si(1) bond lengths. There are four shorter (2.69 Å) and two longer (2.95 Å) Hf(1)-Si(2) bond lengths. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 8-coordinate geometry to four equivalent Hf(1) and four equivalent Si(1) atoms. All Si(1)-Si(1) bond lengths are 2.58 Å. In the second Si site, Si(2) is bonded in a 8-coordinate geometry to six equivalent Hf(1) and two equivalent Si(2) atoms. Both Si(2)-Si(2) bond lengths are 2.39 Å.
