Here is a Z-matrix for C60 that I made some time
ago for G92. The problem that my copy of G92 can 
not handle the Ih symmetry and default to C1 (no 
symmetry). The exact value of the angle a is 
63.43494886  By truncating the value of the angle 
a to 63.43 you can force  G92 to use D5D symmetry
 
Note: you must fix the two angles a and w.
      you can optimized distances f and d only
      f is the distance from the center of the C60 to the
        center of any pentagon
      d is the distance fron the center of pentagon to any
        of its Carbons.
