Any suggestion about chemistry-tools

[Nickel Cobalt <angelerosster@gmail.com>]

Hi folks,
I'm a chemistry teacher in senior school. For several years I used ACD/sketch in
windows, but now I am using debian4.0 stable. 

I want to know are there something tools like ACD/sketch in debian,
which must have following feathers:
  a. moleculer designer
  b. 3D view and rotation
  c. pretty output with OpenOffice and/or PDF, as well as latex
  d. some moleculer template such as ACD/sketch
  e. bond length & bond angle caculation, etc.
Any suggestion will be apreciate!

Regards,
