Hi all,

I often have to use the mhchem latex package to write chemical formulas,
and I have teh following export issue.

If I have this in an org file:

\ce{ABO_3}

\ce{ABO_{3-\delta}}

this exports as
\ce{ABO_3}

\ce\{ABO$_{\text{3-}\delta}$\}

The first one is fine, but the second one is not.  The nested {} seems to
mess it up. Is there a way to get this to export correctly?

thanks,

John

Hmm.  I've played around with this a little, and the best solution I've
got is to use an explicit fallback to LaTeX, like:

#+LATEX: \ce{ABO_{3-\delta}}

...or whatever literal LaTeX is the right output for your situation.
(What is the correct export output in this case?  In particular, should
the contents of the subscript be in math mode?)

The problem does indeed seem to be the embedded braces...I'm guessing
this is an inherent limitation, resulting form the fact that Org uses
regular expressions to recognize LaTeX expressions.

If this is something you need to do all the time, and the #+LATEX syntax
doesn't work for you (e.g. if you also need HTML export), you could look
into an Org macro or an export filter. 

Best,
Richard

You could use snippets.  If you prefer the macro syntax you could also
use that. . .  

   #+MACRO: ce @@latex:ce($1)@@
   @@latex:ce{ABO_{3-\delta}}@@
   {{{ce(ABO_{3-\delta})}}}

-- 
This is the kind of tedious nonsense up with which I will not put

Thanks. I was going crazy looking for the snippet syntax!

I've taken to using \( \) around LaTeX stuff. I also have:

#+options: tex:t

so that might be required. I tried your example, and I get an
undefined control sequence error (not sure why...), but it seems to
look right in the PDF. Just another option that might work for you
(maybe less typing for one-off situations?).

\(\ce{ABO_{3-\delta}}\)

Thanks for all the ideas. In the end I found the best way is to use ^:{} as
options, and then use regular subscripts. For chemical formulas works fine.
So that is ABO_{3} and ABO_{3-\delta}.
