Sulfide is an angular functional group, the C–S–C angle approaching 90° The C–S bonds are about 180 pm. For the prototype, dimethylsulfide, the C-S-C angles is 99°, which is smaller than the C-O-C angle in ether (~110°). The C-S distance in dimethylsulfide is 1.81 Å. Sulfides are characterized by their strong odors, which are similar to thiol odor. This odor limits the applications of volatile sulfides.
