08/2007 | Zeitschrift für Physikalische Chemie, Oldenbourg WissenschaftsverlagA crystallographic review of arsenic sulfides: effects of chemical variations and changes induced by exposure to light
Crystal data for natural and synthetic arsenic sulfides are reported and discussed. Most of them [α- and β-dimorphite, realgar, β-As4S4 phase, pararealgar, Kutoglu’s As4S4(II) phase, alacranite, uzonite, orthorhombic As4S5 phase] have a crystal structure consisting of a packing of cage-like, covalently bonded As4Sn (n = 3, 4 and 5) molecules held together by weak interactions of van der Waals character...
