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. In terms of their physical properties they resemble ethers, but are less volatile, higher melting, and less hydrophilic.  These properties follow from the polarizability of the divalent sulfur center, which is greater than that for oxygen in ethers.
