Abstract

PbAs2S4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Pb2+ is bonded in a 6-coordinate geometry to six S2- atoms. There are a spread of Pb–S bond distances ranging from 2.86–3.13 Å. There are two inequivalent As3+ sites. In the first As3+ site, As3+ is bonded to five S2- atoms to form a mixture of distorted edge and corner-sharing AsS5 square pyramids. There are a spread of As–S bond distances ranging from 2.30–2.76 Å. In the second As3+ site, As3+ is bonded to five S2- atoms to form a mixture of distorted edge and corner-sharing AsS5 square pyramids. There are a spread of As–S bond distances ranging from 2.28–2.96 Å. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded to one Pb2+ and four As3+ atoms to form distorted edge-sharing SAs4Pb square pyramids. In the second S2- site, S2- is bonded in a 5-coordinate geometry to two equivalent Pb2+ and three equivalent As3+ atoms. In the third S2- site, S2- is bonded in a distorted water-like geometry to one Pb2+ and two equivalent As3+ atoms. In the fourth S2- site, S2- is bonded in a 1-coordinate geometry to two equivalent Pb2+ andmore » one As3+ atom.« less
