An octahedral void is called "octahedral" because its shape resembles an octahedron, which is a polyhedron with eight triangular faces. In a crystal lattice, these voids are formed at the center of an octahedral arrangement of atoms, where six atoms are positioned at the corners of the octahedron. This geometric configuration allows for efficient packing and coordination of atoms in a crystalline structure. The term reflects both the shape and the spatial arrangement of the surrounding atoms.
In a cubic close-packed structure, each atom is in contact with 12 nearest neighbors. Each of these atoms has an octahedral void at its center. Therefore, the number of octahedral voids per atom in a cubic close-packed structure is 12.
No. A molecule of octahedral shape is always non-polar
Yes. it has a pseudo octahedral geometry in XeF6
A distorted octahedral structure has a deviation from ideal octahedral symmetry due to factors like ligand size or electronic effects, leading to uneven bond lengths or angles. In contrast, an octahedral structure has perfect symmetry with all bond angles and lengths equal, like in the case of a central metal atom surrounded by six ligands.
Diamond has an octahedral structure, meaning it is composed of two interpenetrating face-centered cubic lattices.

No, an atom cannot occupy both the tetrahedral and octahedral voids simultaneously in a close-packed structure such as a crystal lattice. Each void space can only accommodate a specific number and arrangement of atoms based on the structure of the lattice.

Octahedral sites are larger than tetrahedral sites because octahedral sites have more space available for an atom or ion to occupy. This is because octahedral sites are formed by six atoms or ions arranged in an octahedral shape, while tetrahedral sites are formed by four atoms or ions arranged in a tetrahedral shape.
electron-pair geometry is octahedral with no LPs and the molecule geometry is octahedral
In FCC iron, carbon atoms can occupy octahedral sites, contributing to solid solubility. BC iron has fewer octahedral sites available for carbon, limiting solid solubility. Therefore, more carbon can be accommodated in FCC iron despite having a smaller void space.
In the interior there is one octahedral hole for every sphere.
