Abstract

AgInTe2 is Enargite-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are six inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded to four Te2- atoms to form corner-sharing AgTe4 tetrahedra. There are a spread of Ag–Te bond distances ranging from 2.80–2.90 Å. In the second Ag1+ site, Ag1+ is bonded to four Te2- atoms to form AgTe4 tetrahedra that share corners with three equivalent InTe4 tetrahedra and corners with nine AgTe4 tetrahedra. There are a spread of Ag–Te bond distances ranging from 2.80–2.89 Å. In the third Ag1+ site, Ag1+ is bonded to four Te2- atoms to form corner-sharing AgTe4 tetrahedra. There are a spread of Ag–Te bond distances ranging from 2.82–2.90 Å. In the fourth Ag1+ site, Ag1+ is bonded to four Te2- atoms to form corner-sharing AgTe4 tetrahedra. There are a spread of Ag–Te bond distances ranging from 2.84–2.88 Å. In the fifth Ag1+ site, Ag1+ is bonded to four Te2- atoms to form corner-sharing AgTe4 tetrahedra. There are a spread of Ag–Te bond distances ranging from 2.82–2.89 Å. In the sixth Ag1+ site, Ag1+ is bonded to four Te2- atoms to form AgTe4 tetrahedra that share corners with three equivalent InTe4 tetrahedra and corners with nine AgTe4 tetrahedra. There are three shorter (2.83 Å) and one longer (2.84 Å) Ag–Te bond lengths. There are six inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to four Te2- atoms to form InTe4 tetrahedra that share corners with three equivalent AgTe4 tetrahedra and corners with nine InTe4 tetrahedra. There are a spread of In–Te bond distances ranging from 2.75–2.99 Å. In the second In3+ site, In3+ is bonded to four Te2- atoms to form corner-sharing InTe4 tetrahedra. There are a spread of In–Te bond distances ranging from 2.89–2.94 Å. In the third In3+ site, In3+ is bonded to four Te2- atoms to form corner-sharing InTe4 tetrahedra. There are a spread of In–Te bond distances ranging from 2.86–2.96 Å. In the fourth In3+ site, In3+ is bonded to four Te2- atoms to form corner-sharing InTe4 tetrahedra. There are a spread of In–Te bond distances ranging from 2.87–2.96 Å. In the fifth In3+ site, In3+ is bonded to four Te2- atoms to form InTe4 tetrahedra that share corners with three equivalent AgTe4 tetrahedra and corners with nine InTe4 tetrahedra. There are a spread of In–Te bond distances ranging from 2.93–2.97 Å. In the sixth In3+ site, In3+ is bonded to four Te2- atoms to form corner-sharing InTe4 tetrahedra.
