Materials Data on Zr3NbAl12 by Materials Project
Abstract
Zr3NbAl12 is beta Cu3Ti-derived structured and crystallizes in the tetragonal P4mm space group. The structure is three-dimensional. there are three inequivalent Zr sites. In the first Zr site, Zr is bonded to twelve Al atoms to form ZrAl12 cuboctahedra that share corners with four equivalent AlZr4Al8 cuboctahedra, corners with eight ZrAl12 cuboctahedra, edges with four equivalent ZrAl12 cuboctahedra, edges with sixteen AlZr4Al8 cuboctahedra, faces with five ZrAl12 cuboctahedra, and faces with thirteen AlZr4Al8 cuboctahedra. There are a spread of Zr–Al bond distances ranging from 2.82–3.02 Å. In the second Zr site, Zr is bonded to twelve Al atoms to form ZrAl12 cuboctahedra that share corners with four equivalent AlNb4Al8 cuboctahedra, corners with eight ZrAl12 cuboctahedra, edges with four equivalent NbAl12 cuboctahedra, edges with twenty AlZr4Al8 cuboctahedra, faces with five ZrAl12 cuboctahedra, and faces with nine AlZr4Al8 cuboctahedra. There are a spread of Zr–Al bond distances ranging from 2.82–3.00 Å. In the third Zr site, Zr is bonded to twelve Al atoms to form ZrAl12 cuboctahedra that share corners with four equivalent ZrAl12 cuboctahedra, corners with four equivalent NbAl12 cuboctahedra, corners with four equivalent AlZr4Al8 cuboctahedra, edges with four equivalent ZrAl12 cuboctahedra, edges with twenty AlZr2Nb2Al8 cuboctahedra, a faceface with onemore »
