KAG5S3

Potassium pentasilver trisulfide, KAg5S3, was synthesized in supercrit ical ethylenediamine using previously reported techniques [Wood et al. (1992). J. Am. Chem. Sec. 114, 9233-9235]. Dark-red crystals of KAg5S 3 crystallize in the hexagonal space group <P(6)over bar 2c>. The comp ound has an open-channeled structure composed of Ag and S atoms, with K+ cations sitting in the middle of these channels.
