Materials Data on TiZn16 by Materials Project
TiZn16 is Bergman Structure: Mg32(Al,Zn)49 Bergman-derived structured and crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ti is bonded in a 9-coordinate geometry to fifteen Zn atoms. There are a spread of Ti–Zn bond distances ranging from 2.78–2.97 Å. There are seven inequivalent Zn sites. In the first Zn site, Zn is bonded in a 9-coordinate geometry to one Ti and ten Zn atoms. There are a spread of Zn–Zn bond distances ranging from 2.75–3.08 Å. In the second Zn site, Zn is bonded to two equivalent Ti and ten Zn atoms to form ZnTi2Zn10 cuboctahedra that share corners with two equivalent ZnTi2Zn10 cuboctahedra and faces with six equivalent ZnZn12 cuboctahedra. There are a spread of Zn–Zn bond distances ranging from 2.61–2.83 Å. In the third Zn site, Zn is bonded in a 9-coordinate geometry to one Ti and twelve Zn atoms. There are a spread of Zn–Zn bond distances ranging from 2.52–3.13 Å. In the fourth Zn site, Zn is bonded in a 12-coordinate geometry to one Ti and eleven Zn atoms. There are a spread of Zn–Zn bond distances ranging from 2.62–3.17 Å. In the fifth Zn site, Zn is bonded in a 11-coordinate geometry to one Ti and ten Zn atoms. There are a spread of Zn–Zn bond distances ranging from 2.55–2.87 Å. In the sixth Zn site, Zn is bonded in a 10-coordinate geometry to one Ti and eleven Zn atoms. There are one shorter (2.55 Å) and one longer (2.67 Å) Zn–Zn bond lengths. In the seventh Zn site, Zn is bonded to twelve Zn atoms to form distorted ZnZn12 cuboctahedra that share edges with three equivalent ZnZn12 cuboctahedra and faces with four ZnTi2Zn10 cuboctahedra. The Zn–Zn bond length is 2.87 Å.
