Shorter than average C–C bond distances are also possible: alkenes and alkynes have bond lengths of respectively 133 and 120 pm due to increased s-character of the sigma bond. In benzene all bonds have the same length: 139 pm. Carbon–carbon single bonds increased s-character is also notable in the central bond of diacetylene (137 pm) and ...
The carbon–fluorine bond length is typically about 1.35 ångström (1.39 Å in fluoromethane). [1] It is shorter than any other carbon–halogen bond, and shorter than single carbon–nitrogen and carbon–oxygen bonds.

In solid materials, the atomic spacing is described by the bond lengths of its atoms. In ordered solids, the atomic spacing between two bonded atoms is generally around a few ångströms (Å), which is on the order of 10 −10 meters (see Lattice constant ).

Silicon monosulfide is a chemical compound of silicon and sulfur.The chemical formula is SiS. Molecular SiS has been detected at high temperature in the gas phase. [1] The gas phase molecule has an Si-S bondlength of 192.93 pm, this compares to the normal single bond length of 216 pm, [1] [2] and is shorter than the Si=S bond length of around 201 pm reported in an organosilanethione. [1]
However, the alternative structure •O–O• is also inadequate, since it implies single bond character, while the experimentally determined bond length of 121 pm [6] is much shorter than the single bond in hydrogen peroxide (HO–OH) which has a length of 147.5 pm. [7] This indicates that triplet oxygen has a higher bond order.
The shape of the molecule is a distorted trigonal bipyramid, with the oxygen found on the equator. The atoms on the equator have shorter bond lengths than the fluorine atoms on the axis. In the gas-phase, the sulfur oxygen bond is 1.409Å. A S−F bond on the axis has length 1.596Å and the S−F bond on the equator has length 1.539Å.
