Materials Data on Mg(InTe2)2 by Materials Project
Mg(InTe2)2 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. Mg2+ is bonded to four Te2- atoms to form MgTe4 tetrahedra that share corners with eight equivalent InTe4 tetrahedra. There are three shorter (2.83 Å) and one longer (2.84 Å) Mg–Te bond lengths. In3+ is bonded to four Te2- atoms to form InTe4 tetrahedra that share corners with four equivalent MgTe4 tetrahedra and corners with four equivalent InTe4 tetrahedra. All In–Te bond lengths are 2.85 Å. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a distorted trigonal non-coplanar geometry to one Mg2+ and two equivalent In3+ atoms. In the second Te2- site, Te2- is bonded in a distorted trigonal non-coplanar geometry to one Mg2+ and two equivalent In3+ atoms. In the third Te2- site, Te2- is bonded in a distorted trigonal non-coplanar geometry to one Mg2+ and two equivalent In3+ atoms.
