Materials Data on TaNbAl6 by Materials Project
Abstract
TaNbAl6 is beta Cu3Ti-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Ta is bonded to twelve Al atoms to form TaAl12 cuboctahedra that share corners with four equivalent TaAl12 cuboctahedra, corners with eight equivalent AlNb4Al8 cuboctahedra, edges with eight equivalent NbAl12 cuboctahedra, edges with sixteen equivalent AlTa2Nb2Al8 cuboctahedra, faces with four equivalent TaAl12 cuboctahedra, and faces with fourteen AlNb4Al8 cuboctahedra. There are four shorter (2.73 Å) and eight longer (2.88 Å) Ta–Al bond lengths. Nb is bonded to twelve Al atoms to form NbAl12 cuboctahedra that share corners with four equivalent NbAl12 cuboctahedra, corners with eight equivalent AlTa4Al8 cuboctahedra, edges with eight equivalent TaAl12 cuboctahedra, edges with sixteen equivalent AlTa2Nb2Al8 cuboctahedra, faces with four equivalent NbAl12 cuboctahedra, and faces with fourteen AlNb4Al8 cuboctahedra. There are four shorter (2.73 Å) and eight longer (2.89 Å) Nb–Al bond lengths. There are three inequivalent Al sites. In the first Al site, Al is bonded to four equivalent Nb and eight equivalent Al atoms to form AlNb4Al8 cuboctahedra that share corners with four equivalent AlNb4Al8 cuboctahedra, corners with eight equivalent TaAl12 cuboctahedra, edges with twenty-four AlTa4Al8 cuboctahedra, faces with two equivalent TaAl12 cuboctahedra, faces with four equivalent NbAl12more »
