The term "octahedral" is used somewhat loosely by chemists, focusing on the geometry of the bonds to the central atom and not considering differences among the ligands themselves. For example, [Co(NH 3) 6] 3+, which is not octahedral in the mathematical sense due to the orientation of the N−H bonds, is referred to as octahedral. [2]
Examples of the capped octahedral molecular geometry are the heptafluoromolybdate (MoF − 7) and the heptafluorotungstate (WF − 7) ions. [3] [4] The "distorted octahedral geometry" exhibited by some AX 6 E 1 molecules such as xenon hexafluoride (XeF 6) is a variant of this geometry, with the lone pair occupying the "cap" position.
An octahedral compound is a chemical compound having an octahedral molecular geometry. Pages in category "Octahedral compounds" The following 29 pages are in this category, out of 29 total.
Octahedral: Octa-signifies eight, and -hedral relates to a face of a solid, so "octahedral" means "having eight faces". The bond angle is 90 degrees. For example, sulfur hexafluoride (SF 6) is an octahedral molecule. Trigonal pyramidal: A trigonal pyramidal molecule has a pyramid-like shape with a triangular base. Unlike the linear and trigonal ...

Octahedral molecular geometry is a common structural motif for homoleptic metal chloride complexes. Examples include MCl 6 (M = Mo, W), ...
The OsF 6 molecule itself (the form important for the liquid or gas phase) has octahedral molecular geometry, which has point group (O h). The Os–F bond length is 1.827 Å. [ 25 ] Partial hydrolysis of OsF 6 produces OsOF 4 . [ 26 ]
The Ray–Dutt twist is a mechanism proposed for the racemization of octahedral complexes containing three bidentate chelate rings. Such complexes typically adopt an octahedral molecular geometry in their ground states, in which case they possess helical chirality. The pathway entails formation of an intermediate of C 2v point group symmetry. [1]
