Ta Ta In Ag
Ta2AgIn crystallizes in the monoclinic Cm space group. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded to four equivalent Ta(1), four equivalent Ag(1), and four equivalent In(1) atoms to form distorted TaTa4In4Ag4 cuboctahedra that share corners with four equivalent Ta(1)Ta4In4Ag4 cuboctahedra, edges with eight equivalent In(1)Ta8In4 cuboctahedra, faces with four equivalent In(1)Ta8In4 cuboctahedra, and faces with eight equivalent Ta(1)Ta4In4Ag4 cuboctahedra. All Ta(1)-Ta(1) bond lengths are 2.91 Å. There are a spread of Ta(1)-Ag(1) bond distances ranging from 3.53-3.74 Å. There are a spread of Ta(1)-In(1) bond distances ranging from 2.99-3.24 Å. In the second Ta site, Ta(2) is bonded in a 4-coordinate geometry to four equivalent Ag(1) and four equivalent In(1) atoms. There are a spread of Ta(2)-Ag(1) bond distances ranging from 2.19-2.51 Å. There are a spread of Ta(2)-In(1) bond distances ranging from 2.99-3.24 Å. Ag(1) is bonded in a 4-coordinate geometry to four equivalent Ta(1) and four equivalent Ta(2) atoms. In(1) is bonded to four equivalent Ta(1), four equivalent Ta(2), and four equivalent In(1) atoms to form distorted InTa8In4 cuboctahedra that share corners with four equivalent In(1)Ta8In4 cuboctahedra, edges with eight equivalent Ta(1)Ta4In4Ag4 cuboctahedra, faces with four equivalent Ta(1)Ta4In4Ag4 cuboctahedra, and faces with eight equivalent In(1)Ta8In4 cuboctahedra. All In(1)-In(1) bond lengths are 2.91 Å.
