Linear alignment of four sulfur atoms in bis[(8-phenylthio)naphthyl] disulfide: contribution of linear S4 hypervalent four-centre six-electron bond to the structure
Abstract
The four sulfur atoms in bis[8-(phenylthio)naphthyl]-1,1′-disulfide are demonstrated to align linearly by the X-ray crystallographic analysis, where the linear S4 alignment is stabilized by the four-centre six-electron interaction.
