Materials Data on Ba(ZnAs)2 by Materials Project
BaZn2As2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ba2+ is bonded in a 7-coordinate geometry to seven As3- atoms. There are a spread of Ba–As bond distances ranging from 3.32–3.63 Å. There are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to four As3- atoms to form a mixture of edge and corner-sharing ZnAs4 tetrahedra. There are a spread of Zn–As bond distances ranging from 2.56–2.61 Å. In the second Zn2+ site, Zn2+ is bonded to four As3- atoms to form a mixture of edge and corner-sharing ZnAs4 tetrahedra. There are a spread of Zn–As bond distances ranging from 2.53–2.65 Å. There are two inequivalent As3- sites. In the first As3- site, As3- is bonded in a 7-coordinate geometry to three equivalent Ba2+ and four Zn2+ atoms. In the second As3- site, As3- is bonded in a 4-coordinate geometry to four equivalent Ba2+ and four Zn2+ atoms.
