Octahedra. Fig. 16.7 Some configurations of chains with composition MX4
consisting of edge-sharing octahedra Two octahedra sharing one edge
correspond to the composition (MX5μ2 or (MX41X22)2. This is the kind of
structure common ...

Transition Metal Oxides: Surface Chemistry and Catalysis
Although not apparent in these cases, it is sometimes more convenient to discuss
structures with networks of octahedra. The rutile structure is one such case. In this
structure, the sheets of closepacked oxygen ions are rather distorted.

Materials Crystal Chemistry
Due to the vacant sites, octahedra sheets degenerate into three types, cj, 02 and
cj as shown in Fig.3-47. By combining these two notations for the octahedral
sheets for A^O3, the possible stacking modes for A^O3 are (i) -c1c1'-, (ii) -c1c2-
and ...
Relva C. Buchanan, Taeun Park, 1997
A third way of interpreting the NaCl structure is by looking at how these octahedra
link up. The NaCl structure can be described in terms of NaCl6 octahedra sharing
edges. An octahedron has twelve edges, and each one is shared by two ...

Solid State Chemistry and Its Applications
The three anions 5, 7 and 8 are therefore common to the two octahedra. The
coordination environments of the cations in wurtzite and NiAs are emphasized in
Fig. 7.19(0 and (g). Zinc is shown in T+ sites and forms ZnS4 tetrahedra, (0,
which ...

Modern Inorganic Synthetic Chemistry
As a result, O2À and A site cations fall in the cubic closepacked arrangement and
the small B site cations with sixfold coordinates reside in octahedral voids packed
by O2À, forming corner-sharing BO6 octahedra. Meanwhile, the large A site ...

Structure in Nature Is a Strategy for Design
Like the open packing of tetrahedra and octahedra mentioned above, the
diamond structure is again formed with the tetrahedra found at the nodal sites of
the diamond net and the icosahedra functioning as [1 1 1] branches [1 1.3]. The
network ...
