On the Crystal Structure of KInS2-I
Abstract
An X-ray single-crystal structure determination has confirmed that KInS2-I has the TIGaSe2 structure. The bonding in KInS2-I is highly covalent and exhibits both two-dimensional and three-dimensional features. The structure is comprised of layers of vertex-sharing (In4S10) adamantane-like units built of (InS4) tetrahedra. The stacking arrangement of these layers creates channels that contain the potassium ions in distorted trigonal prismatic sites that provide the three-dimensionality of the structure. The covalent nature of the interlayer potassium-sulfur bonding is reflected in the non-micaceous morphology and water-stability of the transparent light-yellow crystals. Keywords: Ternary indium sulfides, Crystal structure.
