ZnSr crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sr is bonded in a 7-coordinate geometry to seven equivalent Zn atoms. There are a spread of Sr–Zn bond distances ranging from 3.34–3.54 Å. Zn is bonded in a 9-coordinate geometry to seven equivalent Sr and two equivalent Zn atoms. Both Zn–Zn bond lengths are 2.68 Å.
SrZn2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sr is bonded in a 12-coordinate geometry to twelve Zn atoms. There are a spread of Sr–Zn bond distances ranging from 3.29–3.47 Å. There are two inequivalent Zn sites.
