Xenon difluoride is a linear molecule with an Xe–F bond length of 197.73 ± 0.15 pm in the vapor stage, and 200 pm in the solid phase. The packing arrangement in solid XeF 2 shows that the fluorine atoms of neighbouring molecules avoid the equatorial region of each XeF 2 molecule.
Xenon oxydifluoride is an inorganic compound with the molecular formula XeOF 2.The first definitive isolation of the compound was published on 3 March 2007, producing it by the previously-examined route of partial hydrolysis of xenon tetrafluoride.

In addition to compounds where xenon forms a chemical bond, xenon can form clathrates—substances where xenon atoms or pairs are trapped by the crystalline lattice of another compound. One example is xenon hydrate (Xe· 5 + 3 ⁄ 4 H 2 O), where xenon atoms occupy vacancies in a lattice of water molecules. [ 32 ]
Molecular geometries can be specified in terms of 'bond lengths', 'bond angles' and 'torsional angles'. The bond length is defined to be the average distance between the nuclei of two atoms bonded together in any given molecule. A bond angle is the angle formed between three atoms across at least two bonds.
Relative bond strengths in pentacoordinated silicon compounds. In A, the Si-O bond length is 1.749Å and the Si-I bond length is 3.734Å; in B, the Si-O bond lengthens to 1.800Å and the Si-Br bond shortens to 3.122Å, and in C, the Si-O bond is the longest at 1.954Å and the Si-Cl bond the shortest at 2.307A.

For molecules with five identical ligands, the axial bond lengths tend to be longer because the ligand atom cannot approach the central atom as closely. As examples, in PF 5 the axial P−F bond length is 158 pm and the equatorial is 152 pm, and in PCl 5 the axial and equatorial are 214 and 202 pm respectively.
The bond angles are 177.6° for F–Xe–O, 114.7° for Xe-O-N, 114.5° for (Xe)O–N–O cis, 118.4° for (Xe)O–N–O trans and 127.1° for O cis –N–O trans. [3] The bond lengths and angles on the xenon atom are similar to that in FXeOSO 2 F and FXeOTeF 5, indicating a polar oxygen bond. The Xe–O–N angle is larger than those in ...
