Database analysis of crystal-structure-determining interactions involving sulphur: implications for the design of organic metals

An analysis using the Cambridge Database of 926 structures in the short-axis range up to 8.0 Å, containing divalent sulphur, Y—S—Z, shows that 77 have short axes less than 4.5 Å and are distinguished by a strongly directional pattern of sulphur–heteroatom interactions.
