Materials Data on ZrSiAs by Materials Project
ZrSiAs crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Zr2+ is bonded in a 4-coordinate geometry to four equivalent Si4- atoms. There are a spread of Zr–Si bond distances ranging from 2.79–2.87 Å. Si4- is bonded in a 8-coordinate geometry to four equivalent Zr2+, two equivalent Si4-, and two equivalent As2+ atoms. Both Si–Si bond lengths are 2.47 Å. Both Si–As bond lengths are 2.68 Å. As2+ is bonded in an L-shaped geometry to two equivalent Si4- atoms.
