Hvhriili:(!ii»n antl homl lengths A rather plausible alternative is the possibility that
the actual state of hybridization is not the same for "trigonal" or "digonal" carbon
in C H as in C — C bonds. The observed bond lengths (those for C- C bonds ...

axis of Type II—[lOlO] Miller indices of directions are also expressed in terms of
four digits. In writing direction indices, the third digit must always equal the
negative ...

Coordination numbers of two (digonal) or three (trigonal) are common, and both
coordination numbers can exist within the same cluster. 4. The actual Cu-S bond
distance is dependent on the coordination number. 5. Short Cu-Cu interactions ...

The cases n : 2 (digonal faces) are very real once we accept the possibility of
curved edges. There are many objects in nature that are digonal polyhedra (for
instance pumpkins, which have r digonal faces meeting at the stem and at the ...
For a digonal carbon to be neutral, two nonbonding electrons must be present in
addition to those participating in the two covalent bonds. A neutral digonal
intermediate, a carbene, is highly electron-deficient (despite its neutrality),
because it ...

From Chemical Topology to Three-Dimensional Geometry
The local structures for different cases of fusion (digonal + digonal; digonal +
trigonal; trigonal + trigonal with parallel orientations; and trigonal + trigonal with
perpendicular orientations) may be depicted as in Figure 5. In principle there may
be ...
