Abstract

The layered compounds RbAg2TeS6 and CsAg 2TeS6 crystallize in the noncentrosymmetric space group P63cm, with a = 19.15 Å, c = 14.64 Å, and V = 4648 Å3 and a = 19.41 Å, c = 14.84 Å, and V = 4839 Å3 , respectively. The structures are composed of neutral [Ag2TeS3] layers alternating with charge-balanced salt layers containing polysulfide chains of [S6]2- and alkali-metal ions. RbAg2- TeS6 and CsAg 2TeS6 are air- and water-stable, wide-band-gap semiconductors (Eg ∼ 2.0 eV) exhibiting nonlinear-optical secondharmonic generation.
