Abstract

The new quaternary compound BaSc3AgS6 has been synthesized at 1000 °C. The compound crystallizes in the space group D2b16-Pnma of the orthorhombic system with eight formula units in a cell of dimensions a = 16.154(3) A ̊, b = 11.108(2) A ̊, c = 10.914(3) A ̊ (T = 115 K), V = 1958.4(7) A ̊3. The structure of the compound was determined from single-crystal X-ray methods. Agreement indices are Rw(F2) = 0.123 for 2022 unique data and 54 variables, R(F) = 0.056 for 1201 observations having Fo2>2σ(Fo2). BaSc3AgS6 has a three-dimensional framework structure with single channels that accommodate Ba2+ cations. Sc3+ cations are octahedrally coordinated whereas Ag+ cations exhibit both square-pyramidal and trigonal-pyramidal coordination.
