Abstract

Sc6AgTe2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are six inequivalent Sc sites. In the first Sc site, Sc is bonded in a 1-coordinate geometry to one Ag and one Te atom. The Sc–Ag bond length is 3.21 Å. The Sc–Te bond length is 2.98 Å. In the second Sc site, Sc is bonded in a 4-coordinate geometry to four Te atoms. There are two shorter (2.96 Å) and two longer (2.98 Å) Sc–Te bond lengths. In the third Sc site, Sc is bonded to three equivalent Ag and two equivalent Te atoms to form distorted ScAg3Te2 trigonal bipyramids that share corners with two equivalent ScAg2Te3 square pyramids, edges with three equivalent ScAg2Te3 square pyramids, and edges with four equivalent ScAg3Te2 trigonal bipyramids. There are two shorter (2.90 Å) and one longer (3.02 Å) Sc–Ag bond lengths. Both Sc–Te bond lengths are 3.00 Å. In the fourth Sc site, Sc is bonded in a 3-coordinate geometry to two equivalent Ag and one Te atom. Both Sc–Ag bond lengths are 2.86 Å. The Sc–Te bond length is 3.00 Å. In the fifth Sc site, Sc is bonded to two equivalent Ag and three Te atoms tomore »« less
