Category GEOM_BOND

Name:
'geom_bond'

Description:

   Data items in the GEOM_BOND category record details about
   the bond lengths as calculated from the contents
   of the ATOM, CELL and SYMMETRY data.

Example:

Example 1 - based on data set TOZ of Willis, Beckwith & Tozer [Acta Cryst. (1991), C47, 2276-2277].
