Corner-shared

The crystal stmcture of CrOF has been found to be an infinite three-dimensional array of corner shared CrOF octahedra (57). The species [CrOX ] , ... 

Diphosphate tungsten bronzes (DTB) Cs Hg (P 04)4(W03)gai e chai ge-density wave (CDW) conductors. The framework of Cs contains columns of corner-sharing WO octahedra internked through P O group. Properties of Cs can be tuned via out-of-... 

For a long time the structural classification of the mineral todorokite was uncertain, until Turner and Buseck [4] could demonstrate by HRTEM investigations that the crystal structure of that mineral consists of triple chains of edge-sharing octahedra, which form [3 x 3] tunnels by further corner-sharing. These tunnels are partially filled by Mg2+, Ca2+, Na+, K+, and water (according to the chemical analysis of natural todorokites). In 1988 Post and Bish could perform a Rietveld structure determination from XRD data taken for a sample of natural todorokite [25], This diffraction study confirmed the results of Turner and Buseck. The cations... 

RuF3 can be made by iodine reduction of RuF5. It is obtained as a dark brown powder that contains corner-shared RuF6 octahedra [15], RuC13 exists in a- and /3-phases ... 

Let — fe be the charge of the anion located at a corner shared among several polyhedra. We now postulate the following electrostatic valence principle II. In a stable coordination structure the electric charge of each anion tends to compensate the strength of the electrostatic valence bonds reaching to it from the cations at the centers of the polyhedra of which it forms a corner that is, for each anion... 

Figure 5. An illustration of the first three members of the structural series BisWnOan+a, viewed along [100]. The structures consist of Bi20t sheets separated by one, two, three, etc. (n = 1, 2, 3, etc., respectively), corner-sharing sheets of...

Figure 16 Single cubane-type and corner-shared double cubane-type clusters derivedfrom the incomplete cubane-type sulfido-hydrosulfido cluster [(Cp Ir)3(p3-S)(p2-...

Figure 3.1. Schematic representation of dimensional reduction for a framework of corner-sharing MX6 octahedra. The M and X atoms are represented by black and white spheres, respectively. In a) though d), reaction with AbX incorporates additional X atoms into the M—X framework, progressively reducing the connectedness and effective dimensionality of the M—X framework. In d), after incorporating n units of AbX (n > 2), the structure is reduced to isolated oligomeric or monomeric components. For clarity, the A atoms are not shown in the figure.
